Emdr for panic while driving - what are your experiences?

Currently struggling with panic/intense anxiety while driving, specifically getting intense tachicardia and fear of passing out while on roads where I can't immediately stop. It's making my life incredibly difficult, it's one of the most awful things anxiety has made me experience. This is not linked to a specific trauma event (e.g. not related to an accident) but every time I panic, I sort of "traumatize" myself a bit more and it's making it impossible to drive anywhere besides back roads. I have a history of panic attacks (which mostly stopped years ago) and GAD and have been in various forms of talk therapy for years, but nothing has helped for this specific fear. Recently changed therapists and my new T does EMDR.

I am desperately looking to hear more about people's experiences with EMDR and driving panic: did it help, how long did it take, what advice would you give to someone starting out?
