Something that happened in therapy today

I was at a therapy session earlier this morning and something I've never experience happened. The therapist was leading me into a very difficult memory I had when I was younger, an event that seems to be an enormous cause of a lot of my fear and anxiety toward people. While he was doing this, I felt this spiraling energetic movement in me, almost like I was spinning inside. My anxiety got triggered really strongly for a couple minutes after that but it slowly subsided afterward. This whole day, I've been compulsively distracting myself with food and especially electronics as the emotions I'm feeling right now are really strong. I was just wondering if anyone had any advice or has experienced an energetic movement like this before.

Thank you. :)
