Allergic if it's any help, every single person I know who lost their job went on to something better. I'm not just saying stuff off a cat poster either.
You're probably feeling awful, it's a horrible thing for you to have to cope with. Very tough. But...let's be honest, apart from the money, a rest is no bad thing for any of us, especially given your current pain woes.
Make the most of the time you have off, but give yourself time to get over the shock first. The kitties will LOVE you being at home, so there's one big plus.
I don't know if this works with arthritis, so ignore me if nec, but when I lost my job I did a big supermarket shop and holed up at home with Mr C for a few days to watch TV and sleep off the stress. The shopping was catfood and chocolate, as I recall.
