Determining when to go inpatient

Talked with my case manager today about crap on-call responses and she said that when I'm deciding to bite the bullet and call is most people's hospital-level.

But how do I know where my hospital level is? I've met people who go in if they start to think about suicide--I'd have gone in twenty years ago and would still be there. I have lately been going by "I'll go when I am really going to act on it," but the past few times I have skipped the going and went straight to acting. There's also the other impulsive shyt I do too that gets worse when I get worse.

Today I think I said "I won't go grocery shopping because I don't want to come home and put all my effort into not killing myself because I accidentally got the wrong kind of milk," (in response to "why do you think starving would be better than getting food?") I hope they don't ask about it tomorrow because I'm not going tomorrow either. Can they hospitalize me for this? Eating isn't one of the terms of my discharge so it couldn't be a CD revocation.
(Also I've been in a **** ton of pain lately and if you've ever heard jokes about the pot holes and frost heaves on roads in New England, there's no exaggeration. I had to drive somewhere yesterday and had a choice between a big pothole and a bigger one. I had to pull off and put my shoulder back in a good spot after and I think I'm going to need an alignment sooner than I thought. So if I don't want to go get on a bus and get groceries or carry whatever I get on foot a mile, excuse me.)
