Am I too young for a dating site?
No, but you're not ready for one. Let me drop some knowledge on you: most people (all decent people) don't want someone who is going to base their whole identity and sense of self-worth around them. That's unhealthy and it's really hard for another person to handle. You need to stop defining yourself by your relationship status before you will have a shot at something healthy and mutual. You're not "Bl33ds_Blue_and_Silver, nobody's girlfriend and therefore nobody." You're "Bl33ds_Blue_and_Silver, girl who roleplays, loves anime/manga, and is clearly really into something or else why would she bleed colors." You're a whole person with interests, experiences, and traits. You need to embrace all that, wallow in it, be yourself with a vengeance. Which is actually really easy, since you're already yourself, you just need to know it.
Plenty of people in this world didn't date at all until college age, and end up totally fine and happy with someone else. I don't actually know anyone who dated a lot in high school, and I think all but one of my long-term partnered/married friends got together when they were a little older than you. This actually makes a lot of sense, because that's about when people have developed a sense of self and some life goals, and they've stopped playing those insecure adolescent games. See? Be yourself, do your thing, and things will come together better.
If I were you, I'd work on getting comfortable with myself first. Then I'd completely change how I approach dating. Don't go out on the hunt for a man. Rather, go out to get to know people, and if you end up fancying one, you can make your move. Dating's not really all that different from making friends; the more you do, the more people you talk to, the more friends you have, the more friends you'll make. Go forth and befriend. You'll not only have more friends, you'll have more to talk about and you'll get more comfortable with people. This is all about becoming your own person, because that will attract other people to you, because you're awesome and they want to be around you.
