Does my mom have a drinking problem?

The latest incident was when she got very drunk by stealing vodka from my room before a dinner with relatives and we only found out as she started screaming and crying in the car on the way to dinner. Obviously we turned around.

At home (we all live together) I had to stay with her in bed as I wanted to keep her hydrated and was worried she’d asphyxiate if she vomited but she proceeds to say very difficult things to me like “I hate my son.” and “You only love me because you have to.” and “I want god to take my life.”. I know it’s not her but it’s difficult to hear.

I don’t know what to make of this as the truly bad incidents happen less than a few times a year Last time it a fundraising event I had spent all year helping to organise where she got so drunk that she vomited all over the car on the way home. She drinks at home but not much at all and goes a lot of the time without.

My parents talked about it but neither of them think it’s really a problem. I suggested that we remove the liquor in the house, given her contacts to counsellors she can talk to, but she hasn’t taken up either offer. She did say that she’ll seek help the next time it happens but I feel like that’s planning for failure. My concern is that there’s a negative progression as this time she took alcohol from my room (not hers), drank during the day, and was so inconsolable in the car that I was worried for our safety while we were trapped on the highway.

Once again this happens only a few times a year but beyond what I’ve done I don’t know what to do. What else can I do? Does she have a problem?
