Welcome to the board. I think reaching out to others and seeking more information is definitely the right place to start for making your life better. Remember, knowledge is power, so learn, learn, learn. Get all the books you can from the library and read them. Seek out good, knowledgeable people and learn from them. Get skills.
It sounds like you are still having trouble with your parents. That's not uncommon at your age (or any age, really), but remember that you are an adult and you have the right to act like one. I think parents sometimes have trouble seeing their kids as adults instead of children--they're so used to their kids being, well, kids. I look at my teenager and I flash back to when he was just a wee little fellow. You may have to go above and beyond in acting like an adult in order to get your parents to treat you like an adult.
Good luck
