Feeling shame of what I did drunk

Hi everyone, I recently had a relapse after having 100 something days sober and it was so bad. I sent a guy I dated for 4 months an extremely hateful text message- completely below the belt blows. I was mortified and shocked when I read it, I was in a complete blackout. I turn into someone evil when I drink. I’m soooo mean. I don’t physically fight anyone but I’m hurtful with words.

I’m working with a sponsor again and attending meetings everyday. I just keep questioning if I’m truly a bad person? Those thoughts were inside of me. Any advice would be helpful.

Thanks so much
