Hi @Former-Member .....
There is some classic general advice for delaying angry responses .... like counting to 10 silently before speaking, to try to get a handle on it before spouting off, or punching a pillow, or going and pulling 100 weeds out of the garden ..... that sort of thing.
I suppose these activities have been put forward to you already ?
My hubby has anger / rage / control issues tied in with his eating disordered behaviour. While it is all undiagnosed as yet, I don’t have any insight for you through our circumstances, other than that might be one reason why we have the 7/7 exercise, and restricted menu, and chew/spit happening. Redirecting behaviour, as opposed to misdirecting it, may help to control it, and I think my mr. is doing that ..... especially since being told by a mental health team that he can’t yell at and micromanage our young adult kids. It’s like it has to channel somewhere.
Do you go walking ? That is one of my strategies for managing distress, and I think I have trained myself to calm down by listening to popular piano music ..... it seems to be a trigger for calming me now, after turning to it to block out distress across a few years.
