When I get like you are describing, I try and take a deep breath and not think too far into the future. Try and keep it in the day. If you are unsure about going back to work, give yourself some time before deciding. With regards to him relapsing, try not to think that way because it will drive you nuts. Prepare the best you can and then try to let it go (I know easier said then done).
Now go get yourself a mani/pedi because that always helps!!
