you're probably crying for yourself and the poster... sometimes, it doesn't matter though as long as you can get your emotions out... I sometimes get like that when I'm really 'aware' of things, like my life and how bad things are or what I really want etc... or you know how people can cry when they hear of someone dying even if they didn't know the person? they might very well be crying for their own losses, someone close to them, and not the actual person or the things the person represented but in the end it conveys that you care... I don't know if reading the triggering posts or continuing to read them is the right answer, I think only you know what's best for you.. but we're with you whichever way and hopefully you can make some sense out of this emotional rollercoaster for your own sake... I remember a few times when I was laughing hysterically and then broke out into uncontrollable tears... it was the weirdest experience, but I think it was all the emotions building up, stuck inside... maybe you're going through a similar thing???
