Please, please answer. I just don't know what to do anymore. :'(?

I definitely know how it feels to not be on the same page as your parents/step parents. I would suggest you try to spend more time with your aunt, and if you can, maybe try to move there. You should attempt to muster up the courage to talk to your dad. I know it will be hard, but he should know how you're feeling. I am very sorry for the passing of your mother.. I cannot imagine what you are going through. God bless you
