From today on, I make mywards, I am determined to practice writing twice a day.

I searched and a few sites said "from today on" is grammatically correct, but it's not very common and I think people would see it as an error.

I understandknow writing is my weakness one in all of thebiggest weak-point out of everything in English aspect.

It took a while to figure out good wording. I didn't want to change your sentence too much, but ended up having to so it'd sound natural.

I don't know which onat else could help me get better but practiceing everyday.

Or: "I don't know what else can help me more than practicing every day". These sentences have different meanings, so it depends what you're going for. If you don't understand the difference, I can try to explain.

I have no friends who is foreigndon't have any foreign friends, and the courses on the websitesline doesn't suit me at all.

I a'm lonely and I want someone who's also is a English learner to accompany me.

I added contractions because it makes it sound much more natural and less robotic.

Every time I get the feedback withsaying I made a lot of mistakes I have made, I feel really upset.

I will get some paid courses if my writing doesn't improve whithin/after a month.

From (now/today) on, I make my determine've decided to practice writing twice a day.

"From today on" isn't wrong, but "From now on" is more natural.

I don't know which one cwould help me better but I will practice everyday.

Not fully sure what you meant here, so had to guess a bit.

I have no friends who is(that/who) are foreign and the courses on the websitesline doesn't suit me at all.

"who is" is one _one_ person, since "friends" is plural you can't use it.

You will sometimes hear native speakers say "who are", but I think that's not formally correct. Generally "that are" is considered better here.

Don't be sad! The mistakes are only small grammatical errors that I see a lot of native speakers make too :)

Oh no! I’m sorry you feel upset. But mistakes aren’t bad things, they’re just opportunities to learn.
