You are amazing just the way you are, and in a few years you'll find out there is a guy who thinks you're hot as hell even with no makeup on and hair a mess. But that guy is not you-know-who. Don't ask him out. You'll only regret how you tried to change yourself for him.

 You're life will get better. Believe me.

 Don not give up hope. Ever. Believe in yourself. You are not wrong. Everything will get better.

 Do not be to needy with women. There is a game you must play it. Do not take the labels on pill or supplement bottles as a joke. Be very very careful when taking anti-depressants and to not combine them with anything unless its surely safe. Do not go to the dermatologist or change diet. Stretch legs

 For the love of God, ask her out. Even if she rejects you it will be better than the regret.

 fight back

 300 characters is no where near enough to give you the advice you need. But if there were ONE thing you should know, I would make it two and tell you to be strong and to be kind.

 You're not gay. Stop worrying about it.
