Dealing with an alcoholic mother

My mother is an alcoholic and angry alcoholic and it has gotten worse! She makes our lives a living HELL! She Recently got fired from her job for this very issue. Please help me i need advice! Initially I moved in to help her with the bills b/c my dad couldn’t deal with her so he did what useless person would do and walked away without supporting my siblings financially and now I am stuck with all the bills I feel stuck because I want to walk away but I don’t want to leave my siblings here they are still young but I just can’t deal with it anymore. She gets drunk EVERYDAY morning until night while I am at work and I come home to her screaming and yelling and breaking down doors & at night it’s hard to sleep b/c she will sleep and wake up drunk and it’s the same cycle. I don’t know what I did to deserve a mother like this I wouldn’t wish this on my worst enemy! It’s draining, depressing & exhausting. I try not to but I sometimes wish she would be gone so we can live in peace and I hate that it has gotten to this but honestly the real her when she is sober hasn’t been around for a long time so it wouldn’t hurt if she is gone. No worries
