I need a vacation.

So, how do you balance life when one person is sooooo needy and helpless. I don't know why she is so difficult to deal with, but I have talked to others in my situation and they have very similar experiences. As primary care givers we are belittled, emotionally abused, treated with no appreciation or respect and are given literally no help from the rest of the children, yet we are the bad guys while our siblings are thought of as perfection. I am so completely exhausted and have NO tolerance anymore with her self pity. She always has to be the center of attention and will make up stuff to bring the attention back to her. OMG!
