I was actually just going to say that perhaps you can learn an instrument. I see aries beat me to it. It really does help with the kind of situation you are in. I was, and still am, in your situation somewhat and learning and playing an instrument has helped me so much, I don’t know what I would have done without it. And, if that doesn’t look appealing to you, any of aries’ other suggestions are great, too. Princess Eagle’s are terrific as well.
But definitely try something. From personal experience, it is not healthy for a teenager to not have anything constructive to do. Hope you find something soon!
