"It's not your fault that you're self-centered."

My mother has said plenty of hurtful things to me, but the thing she says most is that I'm selfish. This hurts because I try so hard to respect my parents and not to ask too much of them. 

One day my mom and I were having a talk, and this topic came up. I finally stood up for myself. I outlined exactly why it hurt me when she said that, and I asked her to try to be more conscious of what she says in that regard. Her reply was only:

"Oh honey, you can't help it. All young people are selfish. It's not your fault that you're self-centered."

She didn't apologize, and she never will. It made me realize that I'll never be able to change her mind, and she'll always just see me as a selfish brat who will never appreciate what she does for me.
