Everyone who is learning English has trouble times. Sometimes, if you put yourself to far into a language at to quick a rate, your mind will want to slow down and you will feel less interested.
I don’t remember who, but somebody told me that English was the hardest language in the world, and this is true, to an extent. Meaning, there are so many rules for English that even half the time those who are fluent in it get confused.
To stay motivated at learning it, do what Steve and Sandrinhatico said and take a little break from it for a little while. Don’t feel angry if you don’t get something at first, even the greatest minds of all time had their down times. Just take it in stride, meaning don’t try to do everything at once, take your time learning it.
Don’t force yourself into learning the language at times when you don’t feel motivated. If you do, then your mind will automatically just shut off to any new information on English. So, just realize that you made it this far in the language, and when you don’t feel motivated, just look back at all you have learned.
From what I have read, you seem like you are pretty fluent in the language. There are a couple of words that are messed up, but then again, most English speakers will mess up the same words. If you do need any help, there are always people around who would be willing to help you.

Don’t think you are the only one feeling unmotivated, I’m learning Japanese, and let me tell you, at times it seems like I will never become even partially fluent. Just stay motivated. Sorry for such a long post. Thank you for your time.
