Hi again! Can you perhaps have your mother committed instead to a rehab centre to detox and arrange that she goes back to a new accomadation? If she was gone from the house, it sounds like a lot of your immediate problems would be solved.
Waiting for her liver to give up, etc isn't really an option as you, your sister and your dad are being seriously hurt and affected by her drinking.
Was does your dad think? Does he admit she has a problem? Would he not want to leave her?!! Can you talk to him about it or is he denying it too?
If the situation at home is not going to change then you have every right to look after yourself. I'm sorry, but I don't know how a haemorrage would effect someone - can your dad still have a conversation, etc? If he can, then is he not also responsible for the decision he makes to stay with your mother?
Look after yourself first as the damage done by living with or loving an alcoholic is huge (as you well know, I'm sure).
It has been easier for me to break from my boyfriend and leave him with the consequences of his drinking, as we never lived together yet. I still miss him and can't give up hope that some day he will sort himself out. The longer we have no contact, the more likely this will be. Unfortunately, you can't love an alcoholic the same as you could someone else, so I have had to learn new patterns. Many of these have been of benefit to me in general.
I am the oldest girl of five in an alcoholic home but my parents separated when I was 17. I never realised how deeply this background effected me until recently when dealing with my boyfriend. Through him (as he does love me) I have learnt to let go of thinking I must be responsible for someone elses welfare. It is a very hard thing to do to change behaviours and ideas that one has grown up with but it is possible. Look after yourself and I hope you can find some peace amid the turbulance.
