…it’s possible that I am AFRAID of the feeling of boredom, (whatever that means to me.)
I might be afraid to commit (to anything) due to this, including to things that I want, or wanted, or might want, or want in part, at some time.
you might think this is incredibly infantile, and it might indeed be, if it were you, but it’s an integral part of being adhd, for me, I say.

but then yet again,
it might just be a fear that if you lose interest in something, that THAT isn’t ok, and then you’d feel guilty about THAT, and not guilty that you lost interest, but that you didn’t DESERE to lose interest.
