What to do?

So I am 15 years old, and my sex drive is usually pretty high, but lately it's been even higher than normal. Pleasing myself is becoming boring and I don't know if it's too young for me to try the real thing. I'm not very thin or attractive so it would be a little bit hard for me to find someone to do it with but I could manage. I'm not really looking for a relationship right now, though, as I'm pretty mentally unstable. Advice, anyone?
