Glutton for Pain???

I don't get it, I think I have a sign on my forehead that says, go ahead give me your dirt. I get frustrated when I am busy taking care of my minor children, only to have my adult children dump all over me. My adult children act as if they can't function without mommy coming to the rescue, and when I don't bow to their every whim, they get angry, and verbally abusive. It is my decision that this type of behavior is unacceptable, and maybe we need time away from one another, this hurts tremendously especially with the Holidays coming up. I bend over backwards for them, and put myself to physical discomfort, deprived of sleep, and financially I'm a hole bigger than the Grand Canyon,  and all I get is shade, hostility, and yelled at. This is no way to be. Feeling SAD!!!
