sounds like you have a lot of reason to have some deep anger towards your parents......

It has been a long time since I was your age - so I doubt that I accurately remember how I felt..... it is a turbulent time for anyone. But, I know that one of my therapists has been working with me because my oldest child turned 18 recently and will be off to college soon....... What she said is that it is very normal for ALL kids who are close to moving out to act out more.... kind of wanting to create conflict. Creating an anger buffer between themselves and those who will be left behind (parents/siblings) - with the hidden-hope that it lessens the pain of leaving them.

Maybe that is some of what you are feeling.?.?.?
