Recently,I often suffer have been suffering from sleeplessness.

It is almost 2AM now,and I'm im losing sleep again,. I just can't sleep, because I always think about too many much things.I have too much pressure from my work for I want to join in a trade show, which is full around of foreigners (This sentence was a bit unclear to me, but I think this is the meaning) ,wWhat if I can't understand them? ,wWhat if I don't know how to answer their questions? ,wWhat if my colleagues laugh laughing at me because of about my poor English.,tTheir English is so good,and they.can talk to anybody.I have been studying English very hard lately,reading passages aloud,recite reciting words., and I have paid for one English learning website, with listening, reciting,and reading everday,but I think this is far away from my target,and this all doesn't help too much don't have too much help,mMaybe I should find some really excellent teachers or some helpful friends to help me.
Today I have an interesting lesson about Chinese drama,w.What a shame that I am falling asleep im fallen in sleep,So I will missed one important lesson.
Please,if there are have some kind friends,help me!
