SC, we are all here for you so totally no need to worry if you want to vent.

I think that Pamela and Wide-O have both offered you great and supportive thoughts to sit with.

One practical suggestion - can you order healthy food on-line? The two major super-market chains here both offer this (with delivery) so it might work for you if your PN temporarily means that going to the shops is a bit hard.

Because you are brave and honest I reckon that you will get through this though I respect you way too much to pretend that it will always be easy.
