Sounds like you have a whole lot on your plate right now. Do you have any kind of support system at all? A mom? A friend? A support group you can go to? If you only have a half an hour to unwind by yourself everyday then you have got to make time to unwind and unload with some people who support you and what you're going through. They can help lighten the load.

I'm sorry your daughter disrespected you that way. Just remember, teenagers don't mean what they say. It's just the hormones. When they get older they learn to love you again.
