This feels a bit complicated so I'll try to keep it simple.
My mum (been split up from my dad for 35 years. With 2nd husband of ten years) has always struggled with MH.
She had various nervous breakdowns when I was growing up and it was just me and her living together. It was fucking awful for me as I was a teenager and didn't really get why she was so unpredictable/ crazy. I've tried to help her a lot over the years but I stopped about 10 years ago because I just couldn't take the rollercoaster of emotions. She would have a meltdown and be really REALLY awful to me. I have paid for a lot of counselling for myself to try to sort my head out - and it's worked.
Fast forward to now. She is on ADs and has been for a very long time. She has had bouts of counselling but never really sticks at it. She blames all her problems on everyone else and is a classic 'victim'.
She comes over to help me with childcare for my DCs when I am at work - so she helps on a practical level.
She is prone to the odd bit of bonkers behaviour (sending me distressed text messages late at night about how she isn't good enough to look after my kids etc so she's obviously got very low self esteem). She's very emotional. I am not. She'll cry, rant and rave, tell me in really over the top ways how wonderful and amazing my kids are etc. She'll also lie - I think to cover up things so as not to look bad. She absolutely swore blind she had given up smoking - even though she clearly hadn't (stunk of smoke, cigarettes in her bag etc.). I do believe that she has finally given up now.
Point of this thread though is that she drinks. I don't know how much, but often I'll call her at say 5pm and she'll seem absolutely steaming. Slurring words, telling me the same thing literally 5 times etc. She drinks at my house too - but it'll be weird stuff like drinking wine out of a mug. Warm white wine so she doesn't have to display it in the fridge I guess. My step dad is here with her so I don't fear for the safety of the kids or anything. I assume she is self-medicating for whatever MH issues she has.
I want to talk to her about it because:
My DF drank like a fish and passed away at a relatively early age
I think long term heavy drinking is bad for you (obvs) and I guess worse if you are on other medication
I can't bloody stand dealing with her when she is pissed. I have to listen to her rabbit in about crap several times over and then the next time I speak to her she tells me it all again cos she can't remember any of it.
I think she might risk actually physically hurting herself (falling etc.) and I think I'd feel very guilty if something like that happened and I hadn't tried to talk to her about it.
So... well done for getting this far... and what would you do?
