Grr..... I need sleep but it won't happen. How do I remain sain w/o sleep?

I don't know if it's because of my husband but sleep won't come. Currently he's in the if I worst depression I've seen from him since he's. beenmedicated. He refuses med changes or inpatient. I think he just doesn't see the possiblity of getting better. We got into an argument that I hid all the meds and sharp objects at 4 am. So I'm probably not sleeping because I'm worried about him.

OR

It's because my son is only taking 2-4 hr naps w melitonon before he bursts in to the room "Cramer style" to tell me about the latest mindcraft thing he made or ask I want anything to eat because he's cooking. I swear it's less than every 5 min. He's a locus when it comes to food right now. So I have to be up while he cooks, yes it's him having to cook or he's really cranky. By the way cooking, raiding the frige, and mindcraft at the same time doesn't work.

I'm tired, cranky, and at this point want to lock myself in a closet with a few hour nap.

How do I get that few hours nap or keep from going into an episode again w.o. sleep ?
