My parents (mainly my mom) insist on spouting off derogatory remarks. A few examples:

Are you sure you aren't just making up depression to get out of doing work?
Therapy is BS, don't do it.
I'm so jealous of my friends, I wish I had a son like theirs.
You're never going to amount to anything in life.

How do I tune this out/deal with this? I've always thought of my parents as rational and caring beings but now I just... don't. Every time I hear something like this from them it makes me feel terrible and a lot worse.
