The hospital will give you a medical excuse that doesn't give any information about why you were in the hospital.

I was terrified of the hospital for many years. I"ve been 5 times now and it's not big deal. In fact it usually is a relief to get there and know I'm safe.

It's fine to talk to your therapist about suicidal ideation. They are used to it and if they locked up everyone who talked about it they'd need a lot more hospital beds. I've gradually learned to tell my therapist all about those feelings to the point that it is just something that we seem to check off a list when I'm not well. I did give him something I thought I might use to hurt myself some months back and I got that back last week, which is a great gauge of my progress lately. There have been other times he has kept things for me and a very long period where my meds were locked in a box and he had the key. So every week I brought the locked box and took a minute of the session to get the meds I needed for the week out of the lock box and then it was locked up. For a while he made sure I wasn't taking extra and then eased up on the supervision although it took 2.5 years before both doctors agreed that I could manage my meds alone again.

I have finally learned to feel comfortable telling him those things and it makes me feel a lot safer.
