it sucks when you find out that the people you thought were your friends, or at the least, were friendly toward you, were really being nice to your face, and scorpions behind it. i am sorry you had to go through it, it is something few people deserve, and it is a trying time. rest assured however, that it comes back on them. the people that they think are their friends really are the same way, as they also have trust issues against each other, due to their behaviors, so trust me, it is a mutually destructive situation on their side. you may have been burned now, but they will face an inferno in their waking lives. you'll get through it, they are trash.
it sucks
