I'm pretty confident that he can handle all this as he knows exactly what's going on even if all the particulars aren't available to you or him yet ...

More than likely y'all will go over it at your next session in an effort to try to figure out what it was that caused the trigger and flashback and reaction to it.

It is frightening when these things happen and often confusing as we aren't always aware of what brought them on.

I'm still sometimes gobsmacked by some of the ones I have, but others come to me now and I'm like, Wow! ... Wonder where that came from (while knowing it's a flashback) and I actually enjoy trying to puzzle it out and place it.

Here's a gentle if, okay ...

In between now and your next session be extra patient, gentle & kind with yourself, and if it might make you feel better until then, you can always call him and let him know you're a bit concerned about your flashback and would like to discuss it at your next session ... Sometimes simply leaving a message on the answering machine helps to ease the worry.
