"Am I doing anything wrong?"
Yeah, you're worrying about what other people's image of you is and seeking validation in all the wrong ways. I'm not going to drop one of those "you're young and naive" lines on you, because I disliked them when I was younger, but self-assurance and self-confidence is something that comes with age.
Many, MANY people (adult or otherwise) fake it in exchange for gaining the real thing. It's to be expected when you're a teenager since with puberty, comes this sudden realization of all these aspects of your personality that you weren't even aware existed before then. So since all of this is suddenly hitting you in your teen years, it comes across to you as being the #1 goal in life.
I can assure you that life gets more complex (for better and worse) once you get situated within yourself. Just don't cheat yourself out of that struggle to gain your OWN self image...it is called a SELF image after all. Prefacing your question with your issue of being self-conscious after a breakup then asking us what we would think of you is doing exactly what I'm talking about: seeking the wrong validation from the wrong sources.
I'm not saying the other answers are the "average idiot", but I will say that it is very easy to fall into this cycle of unmeaningful advice (not saying that the answers so far have done that). But what I'm trying to say is that if I could turn the clock back to your age with what I know now, I would ignore what the "herd" is trying to pressure me into doing and would immediately start developing myself, struggling with being that outcast for the time being, then experience what I do now MUCH sooner than what I ended up doing. I can tell you that I'm super happy and self-reliant for these things, and they just feed off of each other.
So if you want my opinion of you, it's this: you have some growing and learning to do :)
