Your story (life experience) reminds me of the night shift I worked at in Terrell Texas when I was working 2 jobs and going to a local tech college. All I will say is it was bad. You are such a good person to endure what you are going through. You are doing the right thing. Taking care of our aging parents should be the right thing no matter what happened in the past. So many people ship their parents off to an assisted living hell hole and neve bother to check on them. EVER....It is like waiting to die in prison. Hugs
