Walls closing in quickly

I have so much on my mind lately. I could write it all down, but it would be a novel. But things are about to get a lot harder on us, and considering we're already pretty bad off, I can't wrap my mind around how bad things are going to be. I am desperately looking for evening work and the only probable option I've found is a job that has the hours of 5pm-5am Sun-Wed, on top of watching kids durring the day to make ends meet. So pretty much I'd be working 24 hours straight....wait a minute...when am I supposed to sleep??? But unfortunately I don't have much choice if I want to keep us afloat. See, Charlie has decided he can't take the pain in his knees anymore. I dont blame him, he's gone 5 years with torn ACLs in both knees. This just couldn't be a worse time for him to be off work. But then again, its to the point where it hurts too bad for him to go to work. So for 4-6 weeks at least, he will be out of work...with no money...with bills still coming in... We have plenty of accident insurance that would cover his pay, except this isn't covered under the term 'accident' since the 'accident' happened years ago and he doesn't have short term disabliliy through his work. So the only choice is for me to go to work. I would just work FT durring the night, but I wouldn't make enough so I would still need to watch kids durring the day. And since he'll pretty much be milking the shit out of this ordeal, I'll have to watch our kids, plus daycare kids, plus him, plus take care of the dog, then go to work all night, just to get back home in time for it to start all over again. Its impossible, but I dont know what other choice we/I have. Plus we have Jack's surgery coming up so we are going to have even more medical bills out the wazoo. I just want to scream. I don't know what to do. His 1st appt is Friday at 12:30. Jacks sono appt is tomorrow at 1:15 and we will schedule surgery.
