For over a year now, I have had my first best friend since middle school. I'm not good at making friends, and I'm really not good at social interaction, so the fact that I have one is amazing at all, but the thing is, she's a bully. When she doesn't get her way she pouts and she whines and throws a fit. She leaves me feeling unwanted and alone as if she wasn't even my friend at all. I don't know how to fix it. For example, I really don't want to go to my project grad which is like everyone that's a senior pulling an all-nighter together and we can't leave for the whole night. I hate things like that and I'm not good at social situations so I really am not comfortable doing things like that and she is angry at me and won't talk to me and is trying to guilt me into going. How do I say no if losing her is so easily done?
