It is really important that you trust your wife and let her in. You can't do this by yourself. It's really a bonus that she's a psych RN. She is familiar with the kinds of problems you're having. She couldn't be a very effective nurse if she judged you.

Doctors and therapists are fine, but you only see them a couple of times a month. They can't support you when you're on your own and having one of those dark moments (been there, done that). Even if your wife can't completely understand what's wrong with you, she can be there to support you.

I think the reason you don't want to be admitted to the same hospital where she works is that you don't want her to see you as just another patient. But I don't think that would happen. If you trust her and include her in what's going on, she would see you as her sick husband who needs help and support.

Those are just my thoughts. I hope they help.
