Trev,
That's a powerful feeling you're expressing, and I bet every abused teenager feels that way at some point.  No one is to be trusted, and if anyone seems trustworthy that's just a fraud and it means he wants something.  And what does he want?  What they all want from me - sex.
I know you're not in the mood to be calmed down, and that's okay.  I will just say you aren't alone or freaking out.  Unfortunately, it's a truth about this stuff that in order to get past it we have to go straight through it, as you are doing.  No short cuts.
Much love,
Larry
