I agree, read through this thread quickly. But staying away from it has seemed to do me better than spending too much time. I quickly skim through the newsfeed, and ignore the stuff that's upsetting. I've looked up people and realized it can just lead from one thing to another and eventually there's something upsetting. I find the bad far outweighs any good on Facebook. I'm really thinking of deleting it, but I like to keep up with my kids on there.
Sorry for what you went through Dechan
