I’ll go first: “You have to have children when you’re young,” told to me when I was in my late 20s, with no desire to ever have kids, and no means to support them, by someone divorced multiple times with at least one adult child who does not speak to them.
Also: Responding to “How do I deal with this problem?” questions with “Oh, don’t worry about it, it’s enough that you’re even thinking about it!”
The double-edged anxiety for any given responsibility thing is an ADHD thing? Ah heck.
Yepp, or at least a subgroup of it and/or autism.
And if you’re really “lucky” it turns into PDA, “pathological demand avoidance” or as I prefer to call it “pervasive drive for autonomy”. Worst case you enter fight or flight mode due to any demands on you. My feeling is that it’s a understandable reaction to the feelings of anxiety demands have pushed on you over the years.
