I'm guessing you have chronic lymphocytic leukemia (CLL), which is a relatively indolent or slow-growing cancer that generally isn't treated in early stages, and in later stages is treated with combination chemotherapy.
Having just been diagnosed I have been searching for information and this site has been wonderful. Now I know what I am facing I feel much more optomistic about the future. I have also (about a month ago) been also diagnosed with diverticulitis and colits so it has not been a good time. However, I now know why I have been feeling so awful. Hopefully things will now start to look up.
I'm sorry to read of your diagnosis, but you're not alone-- this site has a sister site in www.supportgroups.com, where there is a non-Hodgkin's lymphoma support forum that might be helpful to you (chronic lymphocytic leukemia is considered the exact same disease as small lymphocytic lymphoma, a non-Hodgkin's lymphoma).
