Betrayal hurts?

I had a close frnd since 3 years but recently she was gaslighting me and I got angry. When she called me I couldn't pick up her call due to exams and then she started ignoring me. She was literally gaslighting me so I lashed out on her. Now she has created her own group and tells them fake stories in order to get sympathy and attention and back bitches about me a lot and is trying to make everyone against me.
