April, I am so sorry to hear of your difficulties. This has been my first boomerang swap and I have enjoyed it so much! I used to hostess swaps when aol had a quilt board but that was years ago and I just don't think I can do it anymore. Spread sheet? I had a tablet where I wrote everyone's name, address and such. Every thing was sent to me then I swapped them out. Hopefully it won't be too long and you will be able to host again.
I think the first thing on your agenda is to get well. Before you know it all this will be behind you and you can hostess again if that is what you want to do.
