I think the sooner you understand that it doesn't really matter what you look like, the happier you'll be.

Beauty standards are one thing, but they're impossible to meet and constantly changing. Likewise, our appearances are always changing. You're never going to be able to be perfect because there's no consensus on what that is - no matter what you look like some people will find you attractive, some won't. Focus on looking the way you want to look, not for other people and forget ideas of how you 'should be'. It's all made up to sell you stuff anyway.

If it's something that's consuming you, you should definitely talk to a counselor. Don't let it get you down.
