Anyone know what's wrong with me?

I am no doctor but i think its normal at 16 to be flooded with all kinds of emotions. You have a lot of hormonal changes going on and you put that with school, parents, boys and everyday stress you are bound to get depressed. It sounds like you are reading into your symptoms to much thus creating half of them. Try to take some "me" time. Do something that makes you feel good about yourself. Personally if you are feeling that bad i think you should tell your parents so they can make a dr's appointment. You should never feel ashamed to talk about how you are feeling or what you are going through.
