Depression or Teenage Hormones? | Ask the Therapist[/url]

I just read this forum and I largely relate to this. The user doesn't say how long he's had this going on but for me it's been for a while but now largely noticeable. I could be down and the next second hyper and happy. My palms also haven't been sweating until recently. I've been nervous a lot but only in this past week. I don't really want to tell my parents because my life is really good and other people have it worse but I don't want to keep feeling this thing dragging me down. When I feel sad I try to go out and do something or listen to happy music but sometimes it doesn't work and if it does I usually feel the same in a short amount of time. Basically this has been noticeable for me and abnormal the past week. My question is if you think it's hormones or something more serious. Thanks.
