I'm 15, and I have to take care of my mother. She's 58 years old, and I've basically been her pyschiatrist my whole life. Now that she's older, I have to be her nurse as well. She had a parcial knee replacement last year, and I took care of her and the household by myself. Now she has to get a second one, a full knee replacement, and she has cried at least 3 times a week for about 2 months now. I just feel hopeless, and I can't do it anymore. Is there anything I can do without hurting her feelings or pride in any way? I am so tired... I just need a way out
