Deal with it.
It sounds cold, but the best thing you can do is to rise above it and take it as a lesson- they're giving you an example in how not to live.
I'm so happy for you that you still love them to death though. That's definitely taking the high road, and that is so rare.
God/Buddha/Brahma/Allah Bless!
PS- If it's really so bad, tell your school counselor. Unless you're being abused, they don't tell anyone, not even your parents. Unless you want them to, of course.
They're trained in teaching people how to deal with stress and, best of all, can be a mediator if you need one.
