Have you just given up?

I've gotten to the point were I don't have anything to give when it comes to my parents. I express my feelings to my mom and I'm being disrespectful. I'm asked to do more and when I do, it's not how they want me to handle it. Its not even about not feeling enough anymore, it just feels like a "damned if I do, damned if I don't" type of feel to it. You want to say something, but then I'm bringing up the past. How am I supposed for forgive and forget that my mother attacked me out of anger and then tell me that you love me? I've got nothing left to give.
