**i posted this in the girl's locker too because i REALLY need some help. so sorry if u saw this already **

my friend just realized she's a bisexual. she's really scared and dunno how to deal with it and she asked me and my girlfriend for some advice. since i'm a bisexual, i'm supposed to be able to help her, right? well i can't
when i realized i was a bisexual i just told everybody and made a joke out of it and people were mostly like "haha i knew it!! " and they treated me the same. but half of the people in my friend's school (we go to different schools) already dislikes her alot because they suspect she's a lesbian. isn't that HORRIBLE?!? anyways, she's afraid of what's gonna happen if people finds out. she's proud that she's bisexual and doesn't really wanna hide it from everyone (trust me, it's freaking HARD to keep this kinda stuff in). so what do you think she should do?? and how should she tell her parents? i haven't told mine yet and i don't think i EVER will, but my friend hates lieing to her parents(such a goody-goody ). please help
oh and we're 16, by-the-way
