Hello, gyuys!

"Gyus" is a typo. It should be "guys," which is the correct spelling.

Today is a great day.

"great day" should have "a" before it, as "a" is needed when referring to a singular countable noun.

Finally, I bought all the stuff for swimming,; it was a necessary deal,purchase because afterin one week, I will go to swimming class!

"Stuff" is a non-countable noun, so we need "the" before it. "Necessary deal" should be changed to "necessary purchase," as "deal" is not the right word here. Also, "after one week" is slightly awkward; "in one week" sounds more natural. The comma after "stuff" should be replaced with a semicolon, as the second clause is independent.

I’m so exacited.

I always sit at the my work table, and I feel that my body desircraves activitiesy!

"The" is unnecessary before "my work table." "Desires activities" sounds awkward; "craves activity" is a more natural expression.

And, you know, I need to throw off my weight a littlelose some weight.

"Throw off" is not the right phrase here. "Lose weight" is the correct expression when talking about reducing weight.

Actually, we have cold weather these days, and I was at the home most parthave been at home most of the time.

At the home" should be "at home." "Most part" is awkward; the correct phrase is "most of the time."

I made plans, went for a short walk, a little,nd did chores.

"A little" should be changed to "a short walk" for clarity. Also, it's grammatically better to add "and" before "did chores."

I feel puritye now in the flat, and it is fantastic!

"Purity" is a noun, but the sentence needs an adjective, so "pure" is the correct form. "Purity" doesn't fit the context here.

And abouts for my plans: I want to write here regularly, and now I want to write so muchmany things!

"About my plans" should be "As for my plans." "So much things" is incorrect; "many things" is the proper phrase for countable items.

And tTherefore, I think, this letter can seems a little chaotic.

"Can seems" is incorrect. The verb "seems" should not be used with "can." "Therefore" should start the sentence without "And."

But now, I want to share just my recent thoughts.

A comma after "now" makes the sentence more natural and improves readability.

I had an interesting experience,. I was at the home, and I was thinking about what to do.

A period is needed between the two clauses. Also, "at the home" should be changed to "at home."

And I decided to watch something… I remembered about one popular serial -how – Squid Game.

"Remembered about" is incorrect. The phrase should be "remembered a popular show." "Serial" is more commonly used for a series that airs episodically, but in this context, "show" is more natural.

So I started this onewatching it.

"This one" sounds awkward when referring to a show. "Watching it" is more appropriate.

After 2 seriepisodes, I felt like I haved no energy.

"Series" should be "episodes" when talking about individual installments of a TV show. Also, the past tense "had" is needed for consistency.

And I didn’t want to do someanything.

"Something" should be changed to "anything" in negative sentences.

It willould be interesting to continue watching, but I felt that it didn’t make me feel better, I guess.

"Will" should be "would" to indicate a hypothetical situation. Also, "make me better" is awkward; "make me feel better" sounds more natural.

It didn’t give mye any scene,se of positive emotions, and I understood that I shouldn’t do things that just takedrain my energy and leave after empty inside meme feeling empty.

"Give my any scene" is unclear. "Give me any sense of positive emotion" makes more sense. "Leave after empty inside me" should be "leave me feeling empty" for clarity and correct grammar.

After this case, I will be observinge how my usual stuffs influence tos me.

Stuffs" is incorrect; "stuff" is uncountable. Also, "influence to me" should be "influences me."

Also, I want to reduce the noicse ofrom information, and music, – you know, this noise from behinde background noise.

"Noice" is a typo; it should be "noise." "Noise from behind" is awkward and unclear; "background noise" is more natural.

I also try to not to focus on my love, I mean onea person who doesn’t share my feelings, unfortunately.

"Try to not" should be "try not to" for correct word order.

Now I can’t let it go, but I think, I just need to be patient, and after some time, I canwill feel at ease and go aheadmove on.

"Feel ease" should be "feel at ease," and "go ahead" is awkward in this context; "move on" fits better.

You know, I couldn’t imagine that I canould attach to a person so easily!

"Can" should be "could" to indicate past ability, and "easy" should be "easily" to use the correct adverb form.

Therefore, I am also thinking about, you know, my interesting life and what I can add to ithis!

"This" should be "it," as it refers to the "life" mentioned earlier.

Dance, sports, meetings… I will include it definitelydefinitely include them.

Sport" should be "sports" to match the plural form. "It" should be "them" because "dance, sports, meetings" is plural.

And I will share about it with you.

"Share about" is incorrect; "share" should be followed directly by the object, "it."

I just don’t want to “bet all my money” at on one person.

The phrase "bet all money" should be "bet all my money," and "at one person" should be "on one person."

I need to be happy just withwith just myself.

"With just myself" sounds more natural.

I think, it i that’s all for today.

"It is all for today" is slightly awkward; "that’s all" is more common.

Have a nice time, and keep in touch!

A comma is needed after "Have a nice time" to separate the clauses properly.

Hello, gyuys!

Today is a great day.

FI finally I bought all the stuff I need for swimming, it was a necessary deal. I had to, because after onext week, I will go tostart swimming class!lessons.

'All the stuff' is quite casual. You could also say all the gear. It's OK in conversation but if you wanted to be more formal, you could say all the equipment.
Make sure you have a full stop at the end of each sentence and a capital letter at the start of each sentence.

I’m so exacited.

Be careful with spelling. Exacted is a completely different meaning.

I always sit at the my work tablemy desk and I feel that my body desires activities!

Work table is usually for crafting or manual activities. Here I would say desk for studying, reading, working.
I feel that my body desires activities is not wrong but it doesn't sound entirely natural. I would say: I sit at my desk for hours every day and I feel that my body needs movement!

And, you know, I need to throw off my weightlose a little weight.

Is that what you mean?

Actually we have cold weather these days, and I was at the home for the most part.

Not wrong but this would sound more natural: Actually it was cold today and I mostly stayed at home.

I made plans, went for a walk a littleshort walk, did chores.

I feel purity now in the flatThe flat feels so clean and tidy now, and it is fantastic!

I know what you mean here but an English speaker wouldn't say it like that. You could say clean and tidy, or clean and fresh.

And about my plans: I want to write here regularly, and now I want to write so muchany things!

And therefore, I think, this letter canmight seems a little chaotic.

But now I just want to share just my recent thoughts.

I had an interesting experience,. I was at the home and I was thinking about what to do.

And I decided to watch something… I remembered hearing about one popular serialK drama - Squid Game.

Series or K drama.

So I started this one.o watch it.

After watching 2 series, I felt like I have no energydrained.

And I didn’t want to do someanything.

You normally wouldn't start a sentence with 'and' but this is quite conversational so I left it.

It will be interesting to continue watching it, but I felt that it didn’'t make me betterfeel good, I guess.

It didn’t give my any scene,make me feel any positive emotions, and I understoorealised that I shouldn’t do things that just takedrain my energy and leave after empty inside meme feeling empty.

I didn't understand what you meant by it didn't give me any scenes.
'Understood' is not wrong but 'realised' would be a better word here.

After this case, I will be observing how my usual stuffs influence to me.

Instead of 'stuff' I would say 'the shows I watch'. You could also add 'and my viewing habits' if you mean both the stuff you watch and how you watch it (for example binge-watching).

Also I want to reduce noice of information, music, you know, this noise from behindall the background noise from watching the news, listening to music, etc.

'Information' do you mean watching / listening to the news?

I also try to not to focus on my love, I mean the one person who doesn’t share my feelings, unfortunately.

Now I can’t let it go just yet, but I think, I just need to be patient and after some time I canwill feel at ease and go aheadmove on.

You know, I couldn’t have imagined that I can attach to persould feel so strongly about someone so easily!

Or you could say, to use your words. I couldn't have imagined that I could get so attached to someone so easily.

Therefore I am also thinking about, you know, my interesting life and what I can add to ithis!

Dance, sport, meetings… I will include it all definitely.

And I will share about itit all with you.

I just don’t want to “beput all my money” aton one person.

I think, it ithat's all for today.
