My mom's been an alcoholic for 3 years. Last year she was sober for 6 months but me and her moved to Oregon at the beginning of the summer and it was fine but she relapsed, and hasn't been able to stay sober longer than about 2 weeks tops before she buys bottle after bottle of tequila. Every time I end up having to call an ambulance to take her to the hospital, every time she says she's not going to drink anymore(i understand alcoholics say this but it's my mom and i can't help but have a little hope every time that it was the last time). This time around, she's drinking non stop with 2 tequila bottles with her at the moment. She refuses to go to the hospital or let me call an ambulance(she agreed the other times), and she's really sick. Last time she relapsed she had a heart attack. I can't do this anymore, i can't watch her kill herself and i have no where to go so it's not like i can leave, and i wouldn't anyway because she's not capable of taking care of herself right now. I threaten to tell my brother that she's drinking(she listens to him the most) so she'll stop or at least go to the hospital but she just wont listen. What do I do? call an ambulance anyway? tell my brother so he will talk to her? she said she wouldnt forgive me if i told him but i dont care anymore because it's gotten too bad now.
