That was the best friend you will ever have. Dont let jealousy and high expectations run your life, go to school, and stop being angry. More good things have happened when you were happy than when you were mad. And please, just accept the fact that he isnt the one, was never, and never will be.

 don't be afraid to ask questions

 You are the way you are, you can't be anyone else, so use what you got, and wear yourself proudly.

 Don't listen to your friends when they give you relationship advice because THEY ARE NOT EVEN IN ONE...how would they know? you're doing just fine

 Don't let him do that.. you know what i mean.. You'll regret it. And you're giving him something you can't get back. Ever.

 Don't date your best friend. He may be sweet, funny, and really great now but after 6 months of going back and forth with you he's only going to leave you and your heart broken.

 Learn to forgive yourself.

 Falling in love with her and moving out of the country made you happy. But now that she's gone you are destroyed. Live your life and follow your personal dreams or else you'll be stuck in an island alone.
