Worriedgirl, it has to come from the doctor. You need to speak with him and ask him if he thinks she has longer than 6 mos. He probably won't want to give a time frame, so ask him for an "educated guess" and tell him you need Hospice help with your mom. Tell him you would really appreciate it if he would recommend hospice or call them or however it works (someone here can tell you.) You can call yourself and get the info, but I know that the doctor has to order it or state that the patient only has 6 mos. to live and should only receive palliative care. After that, Hospice takes care of medications, nursing care, etc. You really do need some help.
I do understand where you are coming from. It's the very thing that made me cut off communication with my mother. However, I was in FL and she was in NY and not sick at the time (aside from alcoholism.) I only lived with her for 7 yrs. of my life (preteen and teen years), so I'm sure that made it easier for me to do.
In your case, I think you just need some help with her.
Hugs,
Connie
