Susan,
For those who aren't use to being on the receiving end of the giving you may find it rewarding. The thing is to let go,,let your friend give you the help you need in the abscence of a family member. With the friend I would let her know what to expect, what scares you, and maybe some of your inner thoughts. I suppose while receiving treatment you could lighten the mood by , if your feeling well enough to do something you both enjoy, not making it a 24/7 discussion on the whole deal..if you are comfortable with her she will surprise you with compassion for your situation. walk softly at first, it will all follow as it should. As my husbands caregiver I have to say I lightened the mood whenever possible, keeping things as normal as possible, knowing the underlying thoughts are on the surface at all times. This helps a whole lot....maybe since your so use to handling it all, you may just find you really don't want to, its nice to have a soul mate who cares...let her carry some of the load!!!
Thanks for sharing your latest issue, I hope others more qualified will follow up as well!!!! Ginger
