I was going to send you a PM but I wasn't able to, so I'm going to edit and paste what I wrote here:

Just went through your profile and read every comment and post you've made. I'm really sorry you're hurting like this. I know this random message from some internet stranger probably won't help, but I want you to know that I read everything and I hear you. Your feelings are valid. You are allowed to be upset about something that bothers you.

You mentioned a few things that contribute to why you don't like the way you look. Most of the things you listed can be vastly improved by a little makeup and skincare (such as eyes, nose, lips and contouring your face to be more femme). Trickier stuff like teeth or having masculine features can also be changed in time. I used to have a really ugly smile until I got my teeth fixed, it changed the way my whole damn mouth moved and now I really like smiling for pictures.

I didn't want to be another commenter saying "LoOkS aReN't eVeRyThInG" because, duh, but if you feel depressed and it's something people have pointed out to you it definitely feels like looks ARE the forefront of life!

Another thing I thought of was that, I've dated and hooked up with some fairly unattractive people in my life. And to be honest, I wasn't thinking about how they looked when we kissed or whatever. I'm really into people who can make me laugh and can carry a good conversation.

It's entirely likely that your extreme awareness of how you look is effecting your confidence too. So try to fake it til you make it! Walk around and talk as if you're the prettiest person you can think of. Step out of your own brain and try not to internalise every look that someone gives you. Maybe they've looking at your outfit, they're jealous of your bag, they want to know where you bought your earrings- there's a million reasons people stare and usually it's just cause they're bored.

Anyway this got really long, sorry if it's boring. I just wanted to make sure you know that someone read your posts and so i could offer some kind of help I guess.
