Sorry this happens. I've had intrusive thoughts too, and they're definitely no fun.

Do these places or memories have a common theme? for example, childhood trauma, or maybe you're remembering a loved one who died. etc. etc.

Mine involve all the anger and upset feelings I've experienced.

Since mine have a common theme, I am working with my therapist to let go of those past "angers". I've discussed what causes these angers, what the angers feel like, and create an action plan for how to let things go.

I'm wondering if yours have a theme of some sort?
