Have you ever tried meditation? I wonder if it would influence how you handle yourself. I think your behaviors are fine, I'm not judging or suggesting you change, but I wonder how it would help.
I have tried meditation and yoga, but I could never get the motivation required to build a habit. One of the main problems with meditation is that it is all about stillness, which can be very hard for somebody with ADHD! I mean, relatively speaking, a shower is a bit like a form of meditation for me, so maybe people of ADHD do practice a form of meditation by engaging in these activities.
It's common to alternate sitting and walking meditation during extended sessions, to my knowledge both in south-east Asia and in Japan.
