Surgery for B on the horizon

So B will be having major back surgery on 2/2.  While I'm still recovering from foot surgery from November, I'm petrified of having B have his surgery.  It's a spinal fusion, which I know is  necessary for the amount of pain he's been in lately.  Plus, at 32, he shouldn't have to be living in pain and not be able to wrestle around with his boys in pain.  It's been tough to watch, but we know it needs to be done.  I'll have to take over all household duties, care 100% primarily for N & D and it all just feels a little overwhelming.  I mean heck, single moms do this all the time, but it doesn't make it any less stressful/difficult to accept.  I know B will be back to a "normal" state in 5-6 mos, but I have a fear that the surgery won't work or that he'll reinjure himself.  B's very stubborn and particular about things, so telling him to slack off on EVERYTHING for an extended period of time will be hard.  I want him to follow doctor's orders but I fear his OCD will get the better of him and he will have done the surgery in vain.  Please keep B (and the rest of our family) in your thoughts and prayers....we'll need them!
