Birth mother in hospital I don’t know how to handle the stress

So first of all I am adopted and my birth mother and I met when I was 12 (12 years ago) I found out shortly after that she has multiple mental disorders and is an alcoholic. I cut contact when I was 20 in order to try and lower my stress and to concentrate on my own wellbeing.

This time last year I got a phone call from the hospital telling me she was in with liver and kidney failure and was in a coma and on dialysis. She stayed in that coma for 6 weeks than woke up and as she was leaving the hospital the doctor told her if she kept drinking she would die.

So now I am 4 weeks pregnant just found out and I’m super excited, only to get another phone call from the hospital saying she’s back in with sever liver and kidney failure and that she had a stroke last night and is back on dialysis in a coma. Doctor says she isn’t going to make it this time.

Mostly I just need help if anyone can tell me how to lower my stress I really want to keep my baby safe and I know stress harms the little bunny.
