That's one of the few I haven't read but I trust TX_Space when he says it's a good one. I would caution though, somewhat in contradiction to TX, take your time. I think we need to be sure we are in the right mindset when we take on something so scary, something we know is going to be disturbing, at leat on some levels.
There are both an intellectual side to our healign, recovery and understanding as well as an emotional side. We have to pay attention to both, but it seems far easier to control the intellectual side than the emotional one. So take your time, maybe read a little and see how it goes. And it's always ok to take a break if needed. Little steps sometimes take us further than big steps. Just a little unsolicited advice. PS I completely understand your apprehensions in opening that box. Good luck - John
