Can someone explain what hospice is/does? [View all]

Like Tab, I have Stage 4 Cancer. Mine is breast cancer which has spread to the lung, liver and several bones. I had one round of chemo, and am on my second round of radiation now (for pain in the right leg). I have been on Anastazole and Faslodex. Neither did much for the cancer. I do not want to do any more chemo, for many reasons.

I live in a nursing home, but hospice *does* come in and work with our residents too. I too want to concentrate on quality of life.
Will hospice help with that? Who administers pain medication if I need it? Will they work that out with the nursing home?
Yes, I should ask someone here, but our administrator seems to be the only one with any answers, and I like to call her "The Invisible Woman" because, except for giving me my monthly bill and for a few moments at breakfast, she is usually not around.
