Gosh, this sure sounds like anhedonia to me. Maybe some boredom thrown into the mix, too? In any event, I totally agree with the sage @MickeyCheeky. Yo certainly are entitled to and should see some sort of therapist or psychiatrist or both. Treatment can and will help you. You should try to talk to your parents again and emphasize that you really feel you need some outside help. I'm sure they'll respond. Don't give up! Things will get better! All the best!
