I was drunk and shoved mom after getting slapped, any way to stop getting shamed?

It happened yesterday night in front of a couple older relatives. A mutual family friend and my sister had to drive me home.

We had a heated verbal exchange, I said too much, not realizing I'm dealing with my Mexican mother. She slapped the heck out of me but to everyone's (even her too) shock, I became enraged and ended up shoving her to the floor. She fell pretty badly and I'm getting shamed by many within my Latino and hispanic family members. Few actually think we're both to blame.

Some religious (I'm really atheist) folks think I'm going to have bad luck in life and that I'm now cursed for doing that. I don't believe in any of that nonsense. I just feel bad for shoving her like that. I would've never reacted like that sober, much less get violent with her. Now she's afraid of me.

How to get rid of this shame?

It's scary to think how much force I must've applied in that shove.
