Could there be something wrong with me?

I completely understand. I am only 15, but I've felt like that my whole life. Unhappy with your appearance and life itself. It will get better, I promise. What helped me is finding something that makes you happy. For me, that was softball. I am in love with the sport and can lose myself in it. I don't have to worry about what family life is like or grades or my appearance. Hobby's help. They really really do. Also, MUSIC. I fell in love with music. Whenever I was upset or depressed, I would jam in the headphones and play scream-o (or whatever suits your tastes!) I could lose myself in the music and forget about everything else. And i refuse to talk to counselors too, but I turned to friends. They helped me so much. Just talking a little. Let them tell you it will be okay, even if you know it wont be. It helps. Good Luck. And please know that I am thinking about you.
