Welcome tinaanit!

Looking at what you wrote I'd say your Russian seems excellent I hope you'll find what you're looking for in here. Well, I'm sure you will.

A few quick notes if you don't mind:

Title: привет всем - I'm sure it was just a typo though

...изучаю английский и русский языки - you listed two languages there, didn't you? But used a singlular язык. Btw, this kind of mistake is one of those errors even natives make from time to time.

Я начала изучать русский язык год назад, но сейчас он мне даётся всё ещё не легко. - There are clearly two clauses there so you need to separate them with a comma. Also, if you see но/а you usually put a comma before them if not always.

All the best to you
