You need a good day for just you, a breather. If you take one occasionally it helps clear out the mind, if you don't you overwhelm. I went through similar situations with my Grandmother. She one day explained to me before she got to bad that she will expect me to take a day here and there for myself, and that she would understand. It's very helpful. I worry about you, I hope your Mom going to a good nursing home will help you out.
