Driving me nuts!

I don't know why I chose to study Japanese when I have not much liking for it. Now I really regret having chose Japanese. There are some 100 alphabets altogether with the full form and short form. I have never felt so difficult learning Indian language, but Japanese is really driving me nuts! I guess maybe it's also because the teacher is teaching quite fast that we (not I) can't follow it. She thinks that we are English majors and so we should learn more than other majors and so she is teaching like an express train. Every time it's because of Japanese that I can't sleep well the night before and when I try to concentrate studying it, nothing goes inside my head. I really don't know what to do now. I guess the only way out is to study it as many time as possible.
