Feeling heartbroken over friendships.

I belong from Dehradun and i am a 22F. I am currently struggling a lot with friendship heartbreaks, I am just looking for someone with whom I can talk and mainly someone I can be friends with. I want a friend. I had this big ass group of friends but because of this one girl (who was also my roommate) everyone in the group chose to believe whatever shit she told about me to them and they all boycotted me. It's a pretty long story but right now I just want a genuine friend.
