I got a lot better at phone calls when I worked on trauma therapy. I’ve always had issues asserting myself and phone calls are sort of a form of saying “hey!! Quit what you’re doing and pay attention to me because I have something important!” which isn’t something I was used to doing or asking for nor did I even think anything I did was important
I distinctly remember developing one when I was around 8. I wanted it then, but it hasn’t shut up since
