My appendix burst and a week after I got out of the hospital, turned out I was allergic to one of the antibiotics so was right back in the ER. My surgeon had commented when I first called him a couple days previously, "well, we know it's not your appendix. . ."

You say you stop doing self care but the self care field is huge. I would work on doing things that get you something you "enjoy" like changing your bed (clean sheets), doing laundry (warm, clean towels and underwear), taking showers (warm, clean, good-smelling self) and throw in a trip to the library if you like to read, for some good/comforting books to read in bed before sleep or buy/rent a new video game http://www.gamefly.com/ ) or movie, etc. and build up a comforting/comfortable repertoire of literal/physical self care options that might help reduce the need for SI? Just turning to something positive when we hurt, for either comfort or distraction can at least get us through the next little bit of time?
