I'm sorry I would tell that woman in no uncertain terms to go F U C K herself if she really thinks you're going to let her flush $600 worth of medication that can be used next month. Tell her that her options are to hold them for you until the following month, or you will hold them for yourself. She can choose one of your two options, or she can make way for another staff with a little more common sense.

I am part of a clinic like what you describe, and if I was in this situation the nurse would be happy to hold them for me.

Maybe give them to your ind.therapist to hold?

If you are Suicidal then it is best not to have extra pills on hand. How do they even know you have them?

Regardless I would not allow them to be tossed. Be assertive and speak calmly and sensibly with the supervisor yourself. I never talk to underlings when they are being unreasonable.
