Scott,
I am really sorry to hear of your loss and the situation that you are in. I pretty much went the way Jamo did except he has more people to watch over. I took care of my Mother and Father the later years of their lives and the last two for my Father were bad. He had heart trouble and was in and out of the hospital it seemed on a weekly basis. And as he grew worse he became almost impossible to get along with. I never loaned them any money but paid all of their debts and built this house that I now live in for them. My mother was very nice right to the end but my Father sometimes made me want to scream at him or something but I would just walk off until I could get calmed down. I can't give you any advice except maybe expect it to get tougher as it goes along. Sorry to word it that way, but do take Jamo's advise as he has laid it out very well. I was also railed at by so called friends because I refused to put my Mother or Father in one of these crappy rest homes they have up here. And boy do I ever remember cleaning up after my Father's messes, especially when he got to the point he couldn't even get up on the bed by himself. Sorry for the long post, but it may help to know that some others have gone through similiar things.
All the best and I hope that things will get better.
Ron
