CC- I can relate not understanding how the people closest to you don't seem to recognize your problem. I don't know if you feel like this, but part of me was glad that, particularly my parents, didn't acknowledge it because it would be embarrassing, but the other part just wonders why. Maybe they are just turning the other cheek, giving you a chance to resolve it yourself, or maybe they too don't want to see it for what it is. If everything "seems" ok, most people don't want to assume and cause problems.
One day you just need to decide that you've had enough, and want to change. It's not easy, but so far, for me, so very worth it.
Good luck and keep reading on here.
