I didn't get P until I was in my 30's, but I have had knee trouble since I was 12 and spent most of high school on and off crutches. I'm definitely not what you would call pretty, and on top of that my brother, who was in a grade ahead of me, was "socially unacceptable". Smart as a whip, but no tact, social graces or manners whatsoever. Add to that the fact that I moved a LOT (I graduated from my 21st school), life in high school for me was the pits, and I couldn't wait to get out. Fortunately I met my best friend in Kindergarten and we are still friends today; closer than sisters.
Coping mechanisms I have found that help are:
1) If you have a talent or interest, no matter how small, go for it. For me, it started with reading, went on to needlework, and dog training, and then on to training horses. You never know where your life may lead. Its something that no one can take from you.
2) People who make fun of you have low self-esteem and do it to make themselves feel better. That's why they travel in packs. You rarely see just one bully unless he's 7 feet tall, weighs 350 pounds and is a body builder.
3) Learn to accept yourself for who you are no matter what. Even though I'm no raving beauty, I think I managed to snag an extremely handsome man! I've never worn make-up, dyed my hair, and only shave my legs if I absolutely have to. My ex married me because I am an interesting person. He didn't divorce me because of my P (actually, I divorced him), and we were happily married for over 20 years. Looks aren't everything. I've seen a lot of beautiful women who open their mouth and ruin a package.

4) Try volunteering. I loved volunteering. Helping others (human or animal) makes you feel better about yourself.
5) If you're truly depressed, you might try seeing a counselor. They can help you with your feelings and give you other coping skills. Finding a youth group (founding one would be even better!), or if you're lucky enough, getting to one of the Flake Breaks would do you wonders! Nobody would care what you looked like and you could all do this face to face and talk about treatments and tips that would make your life easier.
Oh! And Welcome to PHO!
