What are some good hobbies for teens?

I am fourteen years old and I need a hobby! I haven't been sleeping too well lately and I'm pretty sure its because I don't spend my days doing much of anything really. I'm not very flexible, so I can't do dance/cheer/gymnastics. I can't draw very well, and I don't enjoy sewing/knitting/quilting. I can swim, but I'm way too self-conscious to do that for the school or something. I'm not athletic at all. I do enjoy photography, but I need something else since I don't have a very good camera or much money to get a new one. I can't sing at all. I've tried to play guitar and keyboard, but that didn't work. Can anyone help?
