I too echo what ga says! No matter what, GN is too much a part of my life to leave it.
When I was in the midst of breast cancer and all the chemo etc. I did use the Breast Cancer Care forum, and found it really helpful, provided I stuck with the section that applied to me i.e. undergoing treatment. Wandering into other sections for people worse off than me was scary, although I admired the posters immensely. But I could ask the sort of "Has anyone else...." type question, about silly things that were happening to me.
