So sorry for all you went through, AJ. I agree with the others that it's time to focus on your relationship with yourself, not your mother. Put yourself first. Self care. Some therapy.
I have always been triggered by travel also, at least when I go to interesting or romantic place, mostly international. When I was sober for an extended time I found after the first year it wasn't a problem any longer. I just enjoyed the travel, with all the ups and downs, and adventure, that it entails.
