I feel so alone please help!! ?

Okay so first thing that happened was there was a drama banquet and I asked this girl that I don't talk to too much but I was kind of offended when she said it was cancelled but then I found out from Facebook that it still went on but without me. The second thing is there has been so much drama with me and this one girl Tia we were best friends for a while but she said I treated her like sh*t and that I was stealing her friends away. Then she started spreading rumors about my family and my mom. I tried to rationalize with her and say we can b friends we dont have to be enemies, she said she would think about it which really ticked me off because she made a fight that wasn't so big in the first place huge. Also my other friend Nicole took Tias side and said she won't be friends with me unless I make it up to Tia. What should I do?
