Oh my god, i can't belive my grammar so bad,
Yes, the grammar is bad, but you communicate your meaning powerfully. Don't worry! If you are serious about improving, you really can do it. Start by typing the whole essay again in the post below. Use all those corrections from Ana.
If you want to get the proper grammar habits, say each sentence aloud when you type it. You have already become fluent in English; now you just need to find tune it.
Also, use a spellchecker! :-)
