(I’m bad at explaining so sorry)

Hello, so I’ve recently got a diagnosis by my physicist for BPD once I started explain my symptoms (I’ve been her client for over a year now) 
But anyways I have issues with running on auto pilot and I’ve been like that for months but usually it’s fine, nothing bad happens but a few days ago I think I had my first dissociative episode I remember in detail 
I was learning how to drive with my father but when I went down our old neighborhood I just started feeling like I wasn’t in control of myself and felt like I wasn’t me, so while I was driving I started turning slightly to the side and almost hit three parked cars, I didn’t get back to my body (or in focus like if that helps for explaining) I till my father was yelling and had to grab the wheel so we wouldn’t hit the cars (we are safe and nothing was hit)
So what I was wondering is there anywhere to not Dissociate at important times like driving as I do need to learn because public transit isn’t the best here.
Thank you for reading :)
