*Facepalm* Okay look, just because people question whether or not English is your first language dones't mean that you should give up writing. When someone pushes you down, you get back up. Every single time. Because if you don't get back up, that person wins. Get back up okay? Keep writing, get better at it. People suck at something at first, but the more you do it, the easier it gets. I suggest reading some more. Fanfics, books, newspapers, it doesn't really matter what you read, it should help. I also suggest getting Mircosoft Word if you don't have it. It really helps. (It catches my spelling mistakes.)
So, are you going to get back up? Or are you just going to give up?
