Hello Red Daisy
Me too, a late realization that I'd grown up in an alcholic home and much moving of town, county and even country. Also workaholic drawn to stressful and chaotic situations.
I agree that it's a good idea to find out as much as you can. Like you I'm based in the UK and I was saddened and frustrated at the lack of available info and resources for adults from alcoholic homes here in the UK.
Glad to hear that it sounds as though you have a supportive therapist.
All the best,
GetHiking
