EVERYONE makes fun of my appearance?

What I wouldn't give for a pic....

You may well be a late bloomer, so it might actually level out over time...

In the mean time, you could try working out. You can't really do much about your head if you're so certain it's ugly, but you can certainly do lots to your body. I'd recommend a personal trainer and a gym membership, or perhaps (and also more useful in other ways) some time training in Muay Thai or boxing or something. I've done Muay Thai (Thai kickboxing) for years (and done a little regular boxing as well) and I can tell you that the calisthenic strength training and general fitness promoted while conditioning and training yourself to be a fighter will give you some good looks for sure while also giving you provably effective methods to defend yourself... kids can be mean sometimes.

On that note, don't go looking for some Karate dojo or Taekwondo dojang or Kung Fu studio or something... There are some exceptions, particularly certain styles of Karate and Sanda/Sanshou Kung Fu, but those fighting arts have declined quite a bit from whatever progenitor styles were originally developed for emptyhanded combat out of necessity. The moves and training methods are very often altogether suboptimal or outright ineffective and you probably won't get anywhere building yourself that sexy body you're clearly so interested in :P

Oh, and I'll edit this now that I saw the previous poster. He's dead on as well and probably knows lots more about that side of the issue than I do. Dress well, keep yourself clean and carry yourself in such a way that can only be described as "LIKE A BOSS" (without actually being a douche :P)

Ensure your hygiene is impeccable. Use a little cologne, but not too much. Learn about fashion and try to dress similarly--it doesn't require lots of money, just a studied eye for bargains. Workout to gain muscle mass. Study to get good grades. In the long run, looks matter less than money. But money is easy to make if people have willpower and self-control.

And for the record, those who really care a lot if you're good-looking on the outside are usually only good-looking themselves on the outside (i.e., they're ugly inside).

Tell them to take a long walk off a short pier,and before they do take a long look in the mirror as they are surely,no oil painting. Then size them up for the black hear-ted jerks they are,and toss them into the trash where they belong,without a second thought of them.

Change your hairstyle. Wear on some stylish clothes. Be more confident. It will work wonders

Even I'm ugly as hell but I stay positive.
