Looking up advice to deal with fear of confrontation keep getting advice to do martial arts, the problem is i've been training my whole life and still struggle with it.

I've had a fear of confrontation for a long while now, I struggle with it alot and I was looking up advice for it and much of the advice was saying to get into martial arts. The issue is I've been training martial arts my whole life, I trained in tae kwon do in the WT olympic style from 9 to 18 and got my first dan and was working my way up to the second dan till I took a break in college. I've training in muay thai at a solid gym for the past two years, though i've taken a break for surgery. I'd say martial arts is a massive interest of mine and I want to train bjj and wrestling in the future, I do have some grappling training but not enough to say I'm even a novice. I spar regularly at my gym, have done open mats with people from other gyms coming to mine, and enjoy training quite a bit. I didn't get into martial arts to help with my fear of confrontation, I got into cause I genuinely enjoy training and sparring and I love watching mma, kickboxing, boxing, and to a lesser extent bjj and wrestling. Sparring is my favourite day at the gym and I love when I can do it, it doesn't scare me even when going up against someone I know who is going to demolish me. But in "real life" confrontation is really difficult, like even if I'm keenly aware nothing bad is going to happen and there isn't going to be a phyiscal confrontation, its really difficult, some part of me would prefer a physical one cause then atleast my fear would be more justified. Any ideas as to why?
