Please correct me and whatlet me know which more difficult words I can write it?use.

"What" should be "which" because you're asking about specific words.
"Write it" should be "use" because you want to know which words to use, not just write.

EverydayI often I do the same things every day.

"Everyday" is an adjective and should be "every day" (meaning each day, as a noun phrase).
The phrase "often I do" is incorrect word order. The correct order is "I often do".

I usually wake up at 5.:40, but sometimes I wake up at 6.:10 (because I don't want to leave my bed that early).

There should be a colon (:) instead of a full stop when stating the time.
The "sometimes" part needs a comma or conjunction to separate the clauses for clarity.
"Want leave" is incorrect. You need "want to leave", as "want" is a verb that needs the infinitive form of the verb (to + verb).

I brush my theeth and I havtake a shower.

"Theeth" is a spelling mistake. The correct spelling is "teeth."
"Have a shower" is fine, but "take a shower" is more common and natural in many contexts.

I returngo back to my bedroom.

"Return" is not incorrect, but "go back" sounds more natural and colloquial in everyday conversation.
"Bedroom" is fine, but "room" can be used as a general term, and sounds more relaxed in this context.

I get dressed up.

"Dressed up" implies putting on formal clothes or dressing with effort. In this context, you're simply talking about putting on regular clothes, so "get dressed" is the proper expression.

I doapply my make up and I go to school.

"Do my makeup" is understandable but can be made more precise. "Apply my makeup" is the more formal and accurate phrase.
"Make up" should be written as one word, "makeup", when referring to cosmetics.

InAt school, I study and talking with my friends.

"In school" is grammatically correct, but "At school" is the more common phrase when referring to an activity happening in the school setting.
The verb tense "talking" is incorrect here. The correct form is "talk", to match the tense with "study."

After school, I go back toreturn home.

"Go back to home" is incorrect because we don’t use "to" with the word "home." The proper phrasing is "return home."
The comma after "After school" is needed to separate the introductory phrase for clarity.

I havtake a short walk from athe bus stop to my home.

"A bus stop" should be "the bus stop" because you're referring to a specific bus stop (the one you use).
"Take a short walk" is the more common way to describe walking somewhere rather than just "have."

I eathave dinner.

"Eat dinner" is understandable, but "have dinner" is the more natural, idiomatic expression in English.

I relax in my bedroom - I, watching some series and lay at thewhile lying in bed.

"Lay at the bed" should be "lying in bed". "Lay" is a transitive verb, so it doesn't work here; "lie" is the correct verb.
The phrase "watch some series" is fine, but you could be more specific by saying "watch my favorite series".
"Watching" is the present participle form of the verb "watch." In this sentence, it is used to show an ongoing action happening at the same time as the main action (relaxing).

Sometimes I like listening theo music.

You need the preposition "to" after "listening" when referring to music or sounds.

After I relax I going, I study.

"Go study" is not the correct form. It's better to say "I study".
"Relax" should be changed to "relaxing" since it’s a continuous action after the first event (relaxing before studying).

In the evening, I take a shower and I ggo to sleep.

"Go sleep" is incorrect. The correct phrase is "go to sleep" (with the preposition "to").
The comma after "In the evening" is optional but helps with clarity.
