I can understand how it'd be a little uncomfortable discussing something like this while in public.

I've had to learn overtime that most people in public are too caught up in their own world to give much of a damn about what I'm saying (and probably don't hear it).

Regardless, I'm glad you'll get the opportunity to talk about things until you get to see your psychologist and CPN again.

You've probably heard this before but my therapist told me that when I want to hurt myself I could try snapping a rubber band on my wrist for that immediate pain sensation.

I also use the ice cube gripping method from time to time and it helps a little.
