You need to get it into your head that it doesn't matter. I really need to emphasize that point; it <i>doesn't matter</i>. At all. None of these problems actually exist. You're a human being trying to live just like anybody else. Sure, you might not be the most conventionally attractive person out there, but you're still human. Nobody is going to actually fucking care.

And no, you're not the exception to this. Don't think to yourself: "oh, no, that doesn't apply to me. I'm much more ugly than you think. I'm unlovable." No, no matter how 'ugly' you are, I love you. I don't know who you are, but I love you. You've got a beautiful smile. Please remember that. Thank you.
