Need help

My girlfriend left me and left our house because i am a horrible person. She deserves everything possible and i failed as a partner do that. I had an appointment with my therapist, i have an appointment with my psychiatrist and i am going to attend anger management classes. I fight with her over the littlest things and she tries hard not to fight with me about it by keeping to herself and i push and push until we hit the physical points. I know she doesnt deserve any of it. She still loves me as i deffinitely love her and we are still texting and talking everyday. It gives me hope. I am hoping and praying that she can see my continued changes due to medications and classes to help me. I am not a horrible person, but i am a horrible person for treating her wrong. She is everything to me and i want to show her nothing but love and kindess...and support her with everything in life. I want that chance again because i believe i can get there.... anyone have any comments about this. Greatly would help
