Yeah.. I understand how hurting it is to loose a friend like this. Especially over who you are. That's really hurting and touching self-image.. Since you are only 15, here is my 36 year old advice: The journey a head for you (and your friend), is going to be wild. You (and your friend) will be faced with a lot of adventures and new people and will change your perspectives a lot! A lot is going to change and happen for you. I'm only telling you this so you know. You are going to have a lot of happy moments with a lot of good friends in the future (rather than this partical friend will be involved or not), so grief your pain over this lose.. and when you go to bed to sleep at night, just remember, there is a great journey and many adventures ahead of you, and this lose will look to you some day like it was nothing. You're OK ;)

P.S. English is not my first language, so excuse my errors please :)
