Everyday I have been trying hard to  write  something that happened to me. It seems that is really helpful for my English writing. Even if I  am too busy to write, I  attempt to improve. I am writing this just in the  hope that it will  cheer me up and so I persist in writing.

It is possible that I have misinterpreted this part of the sentence "that something happened everyday". I have thought that you were talking about yourself and that you are basically talking about a personal diary in a foreign language. That is why, I have moved the word everyday to the front of the sentence as it makes that thought clear. That is, it is a daily activity that you are talking about.

The letter i when referring to yourself is always written I. It is a name in that case.

Your use of English punctuation is correct. The space after a comma or fullstop is correctly done.

English tense can be very confusing. You are talking about a continuing action so "I was too busy to write" should be "I am too busy to write"

On the whole, this is a good attempt. You have a range of vocabulary, good punctuation and really only minor errors.
