Honey--it doesn't work like that.
Is there an adult you CAN talk to? A school counselor, or a church official?
I doubt your parents are yelling at you and being strict because they don't love you.
Maybe it's a communication problem? Would family counseling possibly help?
The odds of an older child getting adopted are pretty slim, hon. At best, you can probably get someone other than your parents to have guardianship--but that usually works if there is another family member to go to (grandparents, aunts and uncles, etc). What COULD happen is that you go into foster care--but that doesn't mean your situation would get better, necessarily.
What are the REAL problems here?
