Hi after a long period of hardship I have got into my dream university in US. Everything is excellent here, except for a classmate who is very annoying and making my life torturous in several possible ways. He is a close friend of both my roommates and always at home , never lets me sleep , talks loudly. When we are at get togethers he keeps demeaning me , insulting me disguising it as fun pulling the leg. I dunno how to deal with this guy. He is taking away the positive energy and causing lot of mental stress. Please pray my life here becomes smooth.It is very important for me to study well.
