I'm sorry you're hurting.

I'm not on Facebook. Facebook scares me.

If I did ever decide to go on Facebook, it would be under an assumed name. I wouldn't want anyone I've ever known to find me. I'm not completely alone since I'm still married. (My wife's accomplishment... not mine.) But beyond that I'm a recluse in real life... no extended family, no friends nor even acquaintances really, by choice. It works for me because I'm old. I couldn't recommend it for younger people.
Have you considered signing into The Haven now that it has become affiliated with PsychCentral? I don't really know anything about it. I've thought about trying it out myself. But I dislike signing into places on the internet & then finding there's nothing there for me. And one problem I've always had has been that I never seem to be able to find anyone I can really relate to. It is true too, though, that I tend to keep people at arm's length. So I suppose it's my own fault to some extent.
Anyway... I'm just rambling here. I am glad your sister was able to come up with some kind words for you. Yes... people can certainly contradict themselves from time-to-time. Hope you begin feeling better soon... both physically & emotionally.
