It doesn't sound like a situation that one can like? But, not knowing your diagnosis or what meds you were on/how many/how long, etc. and it being school, with all the alarming things that have happened in schools by students with problems, I kind of think your mental health team had to work to help you and keep others as unknowing as possible. Because the situation was so "big" to you, you think it was big with the others, watching, but they probably had no idea what was actually happening so, other than watching you being escorted away, have nothing to "hang on to" in their thoughts about you. Often the police, fire department, etc. are first responders in cases of illness and there's nothing humiliating about their escorting you; I imagine the other students did not know you were locked out or other details.

I would not bother with it anymore since it is over and you have a new pdoc you like and things are going well; I would remember it though and make sure that next time you see the pdoc first before tapering off and work with him, etc. rather than doing things on your own, where those helping you don't know or understand what is going on because you haven't told them, just suddenly surprised them with a situation they didn't know was stable or not.
