"I'm on the verge of a break down/ I'm on the brink of an epic meltdown/ I'm the way to a flatline" Escape the Fate - Let it Go

That kinda sums it up right now, those three lines. I'm pretty lost right now. I'm not sure what exactly to do with myself. Me being bi is starting to be a larger and larger part of my life. I've made a new friend who's absolutely psyched to have another bi friend. (Is it because he's a guy or what?) He's even trying to set me up with this girl he knows, bi and a year younger than me. Problem? I'm not out to my family. Is it even smart to come out to them now? While I'm still living with them and will be for at least two more years? I know Mom and Dad won't mind but my siblings will. They'll be bad mouthing me behind my back and telling all their friends... I don't know if I can face that and be ok. And for any wondering, I am absolutely positive that I'm bi. It isn't a faze, I've known for sure since last summer; that's over a year.

Anyone have any advise here? I'm just spending all my spare time (and then some) thinking about this and any insight would be much appreciated.
