I've asked my T and p-doc if they'd automatically commit me just because I mentioned suicidal thoughts. They both said no, that it would be if I was unable to stop thinking about it for an extended period of time (like more than a couple hours) or if I actually had a plan. I have mentioned fleeting thoughts of suicide before, and they haven't committed me. If you say you had those feelings while panicking, but don't have them now, it should be fine. I agree that you should mention them.
