Dear HumptyDumpty,
At the risk of sounding callous and unfeeling, which I really don't want to do, I have to say that when I read your above post this morning I found it kind of wonderful, in a dark, futile, macabre way. I even felt a slight pressure on my funny bone. There is something darkly humorous about it that improved my own mood, strangely enough.
Be assured I wouldn't say those things unless I'd many times been where you are now, and am quite familiar with how it feels. It basically SUCKS.
Sometimes you just have to say "Screw it", and give up, by which I mean just stop trying, stop thinking, and trudge through the day.
I for one am very glad you woke up from your surgery. ((Many hugs

))
