Pine wall- I’m beginning to think the doctor who told me it’s coping mechanism when I was a teen was right, I still think it is a genetic problem too in my family (maybe not for everybody affected). I don’t think it’s a psychiatric disorder anymore. I also think the problem is exacerbated by caffeine and sugar, tiredness and stress.
Hifiguy- That’s why I chose the title for my post, it’s what I tapped in to google many times trying to find answers, I’m glad you can across it.
You mentioned mindfulness, for me prayer helps me to focus my mind and also keeping busy.
I can suppress this habit but it never goes away, somedays it’s complete hell.
