I'm sorry you're going through this too... please, please hear everyone here who tells you that it's NOT your fault, and you are NOT responsible. You can't control your parents, you can't make them get along, you can't make them sane, sensible people. People are funny like that, but *especially* parents!

The best thing you can do is take care of yourself, be nice to yourself, and work on figuring out what YOU want for yourself and your future.

Good luck...
