Thank you all. It helps to come here and vent a little. Both my sons are level-headed guys that know what is REALLY going on so that helps. There is a lot of back story with my mother that some of you know, so it does get hard at times. Honestly, I think that the way my brother and mother have treated me in the past makes it easier to take care of them in a way. There is not a deep emotional attachment that gets in the way. My oldest boy told me he thinks I must be some kind of a saint. I set him straight on that one! LOL I would not take care of either one of them if there was anyone else in the world that would. I just have to do it for various reasons, like karma and it is just the right thing to do, ya know?
I appreciate all of your kind words and thoughts.
