Sounds like a difficult process, but the desired goal seems to warrant it! Sorry that you are facing this, but I know you and Sharon have the inner srtrengh to do what is needed!
Please depend on me and Bob in any way that we can give you support.
This probably sounds trite, but you and Sharon are in our thoughts and our prayers. You seem to be doing so well, I'm sure that everything you do (regarding your battle with "C") is well thought out. Get well real soon.....then you and Sharon can visit us in NC.
