Snap out of it!!

Doesn't happy time fly? I had a great time in spring break, but now I am supposed to come back to my normal life - go to school, do homework, and study hard. I have been New York for two months, but I found my English has not improved very much. When I went outside or watched TV at home, I couldn’t understand others' talking. I can't express my opinions fluently. When I do my writing homework, I still had a lot of errors in my essays. I am so disappointed myself now. Sometimes I want to give up and come back my hometown. However, I need to snap out of it!! I know I need to keep going rather than staying!!
