Cleft Lip / Palate Support Group
Cleft is a congenital deformity caused by a failure in facial development during gestation. It can be treated with surgery shortly after birth with highly successful results. Cleft occurs in somewhere between one in 600 and one in 800 births. Cleft occurs in several severities and is divided in two major categories: cleft lip and cleft palate.

I totally get you for the school part, and I feel like most of us in this group would feel the same.
Do you have an idea what you'd like to work in later ?
If you don't have career plans, do you have any hobbies ? Shifting your focus away from your cleft issues can be a real self-confidence booster, especially if it's something you like and excel at (comes through practice, ofc :) ).
That's not to say you should run away from your feelings though, maybe see if you could talk about your issues with someone who's empathetic ?
I'd usually recommend this site, but it has been kind of dead lately (and the new design sure didn't help improve that). Maybe try to dig through old threads on here if you haven't already, some have been really helpful or enlightening.
That said, I know that HS kids are probably the worst to deal with (I guess that was what you were hinting at, else ignore this). Try to find a cool group of friends or fuck groups and find nice individuals to hang out with, you'll probably be suprised how nice most people can be when they're not under the "crowd effect".
It gets better and I mean it, even though life can suck real bad at times, there's quite a shift between and after high school.
Good luck !
