I'd leave my family in a heart beat if I could
Why do you want to leave your family?
I really can't stand them anymore, they ruined my youth
You should be more grateful that you even have a family, since many people are not so lucky. You should work on having a more positive relationship with them instead of wanting to get rid of them.
It's good that I'm honest with you.
You're right, your honesty is a good thing, especially in this context.  I can appreciate your desire to be more independent, but you shouldn't be so willing to leave your family entirely.  Just try to see the good parts of every interaction, and appreciate the help and support that you get.
