I'm currently still on the mission to find out which growth syndrome I have, but I have various issues that have caused me equal distress. For once, I have every single facially clincial trait of Acromegaly, proven by x-rays but not by official diagnosis. The severe brow bossing, the huge nose, the swollen lips, the lumpy chin, extremely dense facial stuble, a very wide square jaw, and extreme facial oil and redness. I look like a monster, I really do. About every single facial trait that is the exact opposite of beauty and womanhood, I have it.
So far, I have have two nasal surgeries, both which left my nose severely disfigured by surgical incompetence and malpractice, and my nose is now damaged and sensitive to the point I have to wear a small bandage on it permanently. To ever even slightly resemeble a girl, I need $18,000 worth of surgery and treatments; mainly a brow bossing procedure, a nasal touch-up, skin treatments (hormone therapy and required therapists/endo visitis), and possibly fat/filler injections for my lumpy chin, adding voice therapy and hair removal treatments to that. So, so many boys are born so much prettier than me with absolutely none of the things I have to spend around $18,000 on (Justin Bieber for example could 100% pass as even as a supermodel girl.) I'm not even about celebrities, %50 of the boys I grew up with were simply born without the extremely masculine flaws my potential Acromegaly gave me.
Basically, Acromegaly is when you age extremely beyond your years; I'm in my mid-20's, and people mistake me for being in my 40's. My body has simply aged that much, especially craniofacially. It's extremely distressing, and it happened to the person who hates it the most.
About you having tumors and a deformed face and such, one positive is that according to study, people are at least more respectful toward those who have obvious deformity or handicap, much more than they are to people who don't look exactly deformed but are merely ugly. If you do look fairly deformed, chances are people have actually been nicer to you growing up than they have been to me, as Acromegaly isn't well known at all and merely makes a person look like they're incredibly masculine (which is actually a growth syndrome, just people don't see it as such out of a lack of education.) However, its really the pain of not having a sexual lifestyle and a "popular" lifestyle that's probably what's giving you the exact same pain I'm going through (as even though people are mean to me, it's really lonliness that gets me down), and like me, the inability to pass or look like the gender/appearance you prefer.
What I say is that surgery has come a long way since you were 4, and I would not doubt that there are procedures out there that could minimalize your symptoms in at least some sort of way. Or, as I promote doing myself, if your deformities are truly hard to look at, both for you and other people, wear a cool scarf wrapped around the area, or even wear a decorative mask. There are times where I've simply had to put a mask on to keep from thinking about my extreme appearance, and it works wonders for the confidence; the cool thing about confidence is that if you're truly confident, people may like you even with a weird decorative mask on.
