Welcome to Psych Central, sorry that you are feling so rough, I'm sure no one thinks you are pitiful, but I know depression is very persuasive and constantly gives out that message. I don't know about how normal teens feel, I was never a normal teen and it was such a long time ago too, but my advice would be to try and talk to someone. Maybe your gymnastics coach could help, rather than jumping in and talking about being depressed you could start by talking about struggling with motivation and see where that leads?
