I think it's important for you to be able to do some self care every day. Find little things you can do for yourself and take little timeouts throughout the day.

Will your Mom end up in a nursing home at some point? I ask because I have a friend whose Mom had early onset Alzheimer's and she tried with her husband's support to keep her at home. Eventually it became too much and her Mom became quite violent and started to wander. When someone requires constant care it is too much for one person to look after them.

I'm very sorry you are going through this and I hope you get some relief soon. You sound like an awesome person doing so much for your Mom. You need to look after you as well though...
