I think it would change a lot. Maybe not change my LIFE so much, but my confidence to have a life. It would get rid of a lot of the things that constantly bug me, it would make me less insecure. I am embarrassed to smile, I used to laugh a lot when I was younger, but when I realised how bad my teeth were I went through this phase for a long time where I would cover my mouth all the time when I laughed or smiled. I tried to find a way to smile where I could disguise what my teeth really looked like. It also makes me a lot quieter around most people so I don't draw attention. I lost a lot of personality because of my teeth and if only I could fix them I could gain so much back.
Then there is my ears, I am so insecure about them that I always cover them, I always wear headbands when it's up, I hold my hair down when it's windy so people don't see. They're such a hassle to disguise. I did my hair up the other night (without a headband ), and took some photos to remember how my hair looked if I ever have a chance to wear it like that. I was having a not so bad time because my photos didn't turn out too bad (but then a crap load of make up and strategic head angles can disguise a lot). I put one photo on my profile because I think I look okay in it, and that's rare that I'll ever think that. But seeing a lot of flaws hidden gives me such a boost of confidence of what I COULD look like.

That's just 2 examples anyway to point out that it would take so much off my mind, give me more confidence and less to stress out over. I wouldn't be constantly hiding and checking and picking, I'd be able to relax about it a little.
Another thing I've come to realise is that a lot of my flaws, I get from my father. My ears, the bags under my eyes, I look like him when those features are accentuated (hence my last post when I said I sometimes look like a boy). My father is not the most attractive person on the planet, which in turn makes me feel less attractive. And when I met him for the first time his girlfriend (my brothers mother) pointed out that I have a 'pancake face'. That REALLY hit a nerve because I am so insecure about the shape of my face.

And one more thing, the fact I bit my nails. I have tried growing them so many times and almost succeeded this time, but I've recently started biting them a bit and I'm struggling to stop. That makes me feel like a failure.
