Hi kittencat
It is hard to liver sober but I think it's easier than drinking. The big change for me was relaising I was in control of whether I decided to drink or not.
I committed to doing anything else but drinking to deal with life..
The more times I did that the more natural it felt.
I think when we find ourselves incapable of looking after ourselves going somewhere where we can get looked after is a good option - although I realise it's painful for you and I'd guess even more painful for your mom?
Be there for your mom KC - stay sober.
