Hi Justin,
I thought I would reply to your post and say hello. I have sister (twin) with exactly the same issues, borderline, alcohol dependence, depression. Whilst I feel terrible for her I can no longer take the trouble and drama she creates for herself. She has lost so many jobs, she can’t maintain healthy relationships with anyone. Only this week she got lost in a farmers field??? The police had to pick her up she had cut herself on barbed wire fence, couldn’t make work. She constantly phones at all hours drunk. In the last 20 years I don’t know a week where it has been peaceful. I actually find my life a living hell. I went on to the Icarus trust website, I hadn’t heard of them. My sister has had stints in the priory etc but she doesn’t stay or engage.I really sympathise with you and understand when you say it affects the whole family. My parents have given up albeit my mum attends Al non for her own health.
I wish I had some positive advice to give but I don’t, sometimes I just feel there is no better.
Take care
