((((Psyoxy))))
Welcome! There is hope for your mom! Especially if she is ready to get help. I would think that the Salvation Army would be a good place to visit. I am not certain but I think they have a web site. They are big into recovery related programs.
Is there nobody who could help with the kids? Could you take charge of them? I bet they are good girls. You don't say how old you are and what you are doing with your life so I don't know how much you could help.
If an addict is not ready for help it is kind of like beating your head against a wall to try and force them to get clean. I hope she wants help it is out there. I am sure there will some people along soon who know more than I do though hang in there!!
