But then you wouldn't be able to find out what your reason is.. as everything happens for a reason, even you, even me. If you hang around long enough you might be lucky enough to figure out what you were put here for and live it. Can't do that if you were never born!
I get the frustration, I do, but maybe you just need to stop looking in the mirror and judging yourself so harshly based on some set of appearance criteria you've decided you should meet. Stop obsessing about that and free yourself. Do what you do, be who you are, look outward around you and enjoy the joys the world has to offer, and when you're enjoying yourself you'll be putting off good vibes in all directions and you'll catch others enjoying your presence regardless of what you look like so long as you're exuding positivity all around you.
Since we're talking about appearances, have a look at people/kids who've been horribly disfigured in a fire, accident, or war.. they still have fun, smile, and can make others around them smile and enjoy life just as well or better than anyone else can - better because there will most certainly be "aesthetically-typical," people out there who might be caught off guard at first glance, but once they realize this person is still just as valid & valued as any other soul, they'll come around to reacting just the same way as they would to anyone else' smile. It's got to be more challenging for someone who's been disfigured to put on that smile all the time and go at life with a can-do positive attitude, but they still do it, especially kids - because kids haven't been so conditioned by years of marketing by tv/hollywood that convince people they've got to fit a certain mould or they're defective. Kids will adapt so much easier and just be kids - and ditto goes for other kids around them accepting them as equals. There's an awful lot we could learn about how to treat ourselves and each other by observing a group of kids at play.
And in finding comfort on common ground, have you ever attended a gay pride parade event? I've only ever checked one out once, but I've gotta say the best and most valuable part of the whole experience was just watching everyone around (hundreds of thousands of people) just Being Free - being exactly who they are, feeling comfortable, acting however they like, dressing however they like, expressing themselves however they saw fit & w/o fear or worries or anxiety about what anyone else around thinks. That was truly a beautiful thing to witness, and if you've never experienced it I suggest you do - it might just change your perspective on things, especially if/when you find others exactly like yourself attending for the exact same reason.
