When I first started seriously considering I might have ADHD my question was well, do I have ADHD or CPTSD because some stuff is common to both. Lately I've been realizing that the ADHD re-enforces the CPTSD and vice versa.

Really spotted today; emotional dysregulation from either source means things that are frustrating become FRUSTRATING!!1! Obviously the faster I can walk back FRUSTRATING!!1! to frustrating, not insurmountable, is important to avoid the angry meltdown I fear because that'd get me punished (and/or set off even more hypervigilence, with the intensity ramped up).

But; hypervigilence is holding onto fear, because you can't afford to let anything be less than absolutely vital, and if fear isn't itself frustrating it sure sets that up easily.

It's not like weepiness, the other big expression of emotional volubility, or f'goodness' sake joy, wasn't something which would be immediately spotted and punished back there.
