whoa there mrsdork - take a deep breath - a few deep breaths -

first I dont think Rapunzel was in any way saying that this persons actions were right - she was trying to give you some insight into the other side of the argument so lets all be supportive of each other ok

PTSD is a pain in the proverbial and I found that the lack of sleeping - irritablility - flashbacks and the whole rest of the stuff that joyusly goes there with it made me much more likely to flare up if someone did somthing wrong - and NO DOUBT ABOUT IT - she did do sometthing wrong - maybe hse was tired and had been abused by customers that day or management - maybe she was just a little hitler - but it was NOT acceptable behaviour and as you said neither was yours when you pushed the sticker on her head

Its difficult to take a step back when you are angry - so what I do is I try to keep a calm voice and put my point of view - if that doesnt work then I walk away if possible and seperate myself fromthe person who is annoying me - I find big shops triggery too

take care ok and look after yourself - PTSD is a pain but in time hard work (yuk!) and some pain (unfortuantely) it does get better
