Yes, I think it's normal. But you are obviously getting stressed. Take a study break and relax. Have some fun while you're still young.

For when you do feel ready to study again, I recommend that you buy English Grammar in Use by Raymond Murphy (ISBN 9780521532891). It also sounds like you haven't found the right dictionary yet. Maybe you should get a good English-English learner's dictionary, like the Collins Cobuild. You can find its contents at http://www.collinsdictionary.com/dictionary/english

Take care. I hope that everything goes well for you.
