Just wanted to chime in with some words of support. I cannot offer much in the way of wisdom as I am feeling low at the moment and I've decided for once to let myself feel that way instead of ignoring it.
I'll say that I think the others are right - posting here has helped you greatly.
So why stop?
I'm right there with you on the anxiety and obsessive thinking. It's my greatest 180 challenge. It's a helluva challenge too. It takes everything I've got sometimes, so I understand what you are talking about.
