Good luck @Canberramum. I agree with everyone else, you decide what is best for you.
If having houseguests will stress you out then best to be honest, I know I could not have stood that. Everyone just wants to help and feel like they are doing something for you.
For the persistent ones I found small things for them to do so they felt they were helping, supermarket shopping, small housework jobs or making a meal for my hubby. Occasionally I asked someone to drive me to an appointment or pick me up when I was sick or had Peripheral neuropathy.
Except for the first diagnosis appointment, I went to every appointment alone. I could not handle seeing others with worry etched all over their faces and the small talk drives me nuts when I am worried. I am so much better on my own as I can concentrate on breathing and relax more.
The nurses at both chemo and radiation were fantastic and they know what they are doing, I relied on them so much for information.
