Hi TJ,
Re: the possibility of rejection. I can understand how, if you make the step of calling the crisis team (which would be a big one for you, wouldn't it) and they didn't want to give you some help, that might feel like a real knock-back.
But you KNOW that you're not going to be facing complete rejection regardless. You KNOW we're here for you whatever.
And if it's hard for you to make that call (which would be understandable) but you know you need their help...........maybe your wife could do that for you?? I get the feeling she wants to be there for you?
And excellent post from secret on the help they may give you, which wouldn't necessarily need to include hospitalisation. Then again if it did, then all that matters is that you're getting the help you need, right? Nothing else!!
I mean your wife's stood by you through everything (everything you've let out to her) so it's saying to me she just wants the best for you, if I'm right? Then you could always talk to her about the "what if"'s too, if you haven't already.
And work.........well you're much more important than allowing work to stop you getting the help you need. Much more important!! No job is worth keeping feeling the way you're feeling for!!

As for the rat.......well, a call to environmental health?? But until it's sorted "see/imagine the adorable side of it" . Used to keep pet rats and can be so nice, really!!!
I know it's not quite the same...........but just until it's sorted............
