You can have non-risky hypersexuality and it still counts. As long as it inerfers with your daily life. Which it sounds like it is. Bipolar in kids can look different, more like adhd and depression. I'm sure it's imbarassing to talk about hypersexuality it's embarrassing as an adult to talk about it. My son is 15 and he's in the process of getting rediognosed. I'm not sure if he deals with hypersexuality like I did as a kid. If you don't want your parents involved and you have your own transportation I believe you can go to the Dr yourself. He'll probably run tests and refer you to a therapist. Drugs are only there to help you stabilize if you're bipolar. You don't have to talk about your feelings but what stresses you and problem solving. Please see someone if your depression gets so dark that you consider taking your life.
