Just to add. When I say deal with what's going on in that house I don't mean to fix it. When I left home my mother made me feel guilty. I realize now that she was "my" parent and she expected me to be "her" parent - that's dysfunctional. What's going on in your home is NOT your fault. They're adults and you deserve so much more and it sucks but through therapy you'll understand that it is what it is and it's not your problem it's their problems.
