No lectures from me. Questions though, since yeah of course the anticipation of some type of delayed reaction sounds horrendous in and of itself.
This happens with or without being rested?
When you say explosive, is that temper or the anxiety/panic attack is explosive in its onset? You've been treated for depression but not anxiety in the past, am I understanding correctly?
Does your mood go haywire or is it full blown palpitations, sweating, jitters?
