Why do people not get along well with me?

I'm not the best person, but I'm not mean or judgemental. I'm pretty nice, maybe a little energetic or goofy, but I don't see why that's a bad thing. Could it be my looks? http://udontlikewaffles.deviantart.com/gallery/#/d35vfck Am I not picking up something? I feel alone and isolated. I feel weird and out of mind, out of thought. I'm scared and confused. I just want a little comfort.
