How should I support this?

Unfortunately, at the age of 17, Child Protective Service will be very hesitant to get involved, unless your physical abuse is leaving bruises or other marks. Even then, at your age, it is unlikely they will remove you from the home because, simply, there are very few foster homes which would accept a boy your age. If you are indeed being physically abused, the Police are the better option.

Sometimes, grandparents or uncles/aunts can provide a safe place for you to sleep/live for a few weeks, until you can sort out things.

According to your profile, you will turn 18 in a few months. However, it seems to me you might not have the maturity required to live on your own, or even with friends (most 18-year-olds don’t have the necessary maturity).

Part of the problem is that 17-year-old boys do indeed “have an attitude” (I know; I’m a foster dad, and have raised 31 boys in my home). So, whether you realize it or not, your attitude is contributing to the problem in the house. You might not realize it but, as I said, I’ve raised 31 boys, and have seen the 17-year-old attitude problem 31 different times.

I commend your hard work in school, as evidenced by your impressive scores. But I would strongly advise against just running away from the problem. Real men find rational solutions to their problems and don’t run from them.

Can you tell me if you have grandparents or uncles/aunts living nearby, who might be willing to let you stay in their home a few weeks?
