It seems like you escape your inner conflicts by being industrious.

Not professional advice but instead of going, you could halt posting for a moment and focus on your breathing. It will assure you that you are safe, and you can let the conflicts become a bit more aware without feeling overwhelmed by the terror. Do this for some time and you create the space to transform your conflicts.

Meine Hypothese ist, dass die deutsche Mentalität zur Unaufgeregtheit neigt.

Der Grundzustand des Menschen ist Ausgeglichenheit. Es ist daher nicht nur mög­lich, dass Menschen positive Erregung als Ziel zu haben sondern eben auch das Beibehalten der Ausgeglichenheit.

Weisser Spargel ermög­licht eine unaufgeregte Mahlzeit, ist aber andererseits so ungewöhnlich, dass er für Abwechslung sorgt.

Totally. Only that I postponed the thing I had to do for even longer.

Your post made me realize that I postpone because I am afraid of hyperfixating. When I hyperfixate I do things that I don't want to be do, but that have to be done to make them right.

Like I expected, when I finally did what I had to do, I found something that was not right, and spent some additional time on it without being able to let go.

Here is an older thought about it: Could it be that ADHD is an identity thing? Essentially like transsexual but for being and not sex. Hyperfocussing is like wearing a mask, not out of fear of social reactions but from the inability of maintaining my identity. I lost my day by being afraid of experiencing being-dysphoria. It only ends when the fear of the consequences of inaction are bigger than the fears of dysphoria.
