Hey bud.
Well done on posting.
Alcohilism, like addiction is a terrible thing – I don’t need to rattle on about it as you are seeing where it leads in full force right now.
It reads to me like your mum needs urgent help. This needs to be professional help too – it can actually be lethal for a chronic alcoholic to suddenly stop drinking, I say this not to scare you but purely for education.
This is a complicated situation as I can see you mention other issues with mental health and medication, in my humble experience those areas are usually linked with the drinking, but best to speculate later and look at right now.
The first thing is to have her reach out to her GP, if she won’t, you may well have to and you will have to be honest about what’s going on and the severity.
Someone to is that far advanced in alcoholism will need a supervised detox. Acrophobia is an awful condition and likely affecting her reaching out for help.
If she is receptive to any of this, and can get medical help, there is a ton of support she can get into – happy to share this with you but thought I’d focus on here and now as it sounds serious
Start with a GP asap.
