That's rough mate. Of course I don't know your circumstances, but I have had a few rough breaks on this journey. Kicked out of a couple of relationships, lost a job or two, done a few stupid things. I got through I guess because I put first things first, and my sobriety came first because without it, there would be nothing else.
Sorry to hear about your mum too. I hope she is at least comfortable, and no doubt she will be happy to see you sober.
