Life will not always go your way. Sometimes your friends go too far with jokes, next thing you know is that you aren't friends anymore. They joke about my best friend being a girl. They say I am dating her, if your friends are arseholes like that then you shouldn't be friends with them, and so much for friends.
Your friends should be nice and support you with want you want. They should never be a backstabber. My best friend (Sassy) does be nice and support me in what I do no matter what I do wrong. That's what makes a friendship. Sometimes your friends change you into someone you're not. That's the thing, you need to find someone who won't change you.
