I can't be of any help but I just waned to say I'm sorry your mother is having to go through this. But seems like she has a wonderful daughter to help her.
(Hoping you are a girl) If not she has a wonderful Son

Has anyone talked to your mother about surgery to lose weight. I mean I don't know if thats even a option or not but is the problems coming from being overweight? You'll have to forgive me cause I'm not very smart on this subject
Please let us know how everything is going.
Take Care
