@utopia yep I do get that. One tiny little thing or thought or image etc. can turn into a sudden and overwhelming negative reaction. I do know when I am not physically well I can't cope emotionally - and when I am really tired it is worse. I have been trying to avoid tv and music this week as there always seems to be something that triggers a negative reaction. There are certain words that are huge triggers for me - in any situation and in circumstance- none of which you have used - but maybe when in my hyper-vigilant state I make connections in my mind to those!
