I have always sort of noticed this but it became very obvious yesterday when returning to work after a 2 week vacation.
I would say I am more or less anxiety free these days, I've not had a panic attack in roughly 5 years, and just have normal anxiety that everyone has.
But after walking into work yesterday I suddenly became depressed, my personality changed from happy confident to feeling very low, The mood continued through out the day and suddenly lifted after leaving yesterday evening, same process today.
I have done a bit of research and the process is called anchoring, A way to explain this is, say for instance you hear a song on the radio that reminds you of an ex or one that always gets me is when walking past a bakery, and the smell of freshly baked bread always takes me back to my childhood when my mother would bake bread.
Unfortunatly I can't find how to reverse the process.
Work was just one example, if I walk into say the post office I feel rather uneasy, and the reason for this being I once had a panic attack in there,and even though I have recovered the sub concious still sends the signal that danger is present in that particular situation.
Do you get this? Or have you any advice?
Have you ever noticed how certain people / place can trigger of your Anxiety or D
Pear you are right now that I think about it I see that happens to me at the Drs office. I did relate immediatley to your love of fresh baked goods and the smells of childhood and innocence etc. So right away I though maybe I should carry around a fresh loaf a bread to sniff when I get nervous?!? No? well darn I thought you might be on to soemthing. 
I did remember reading about aromatherapy on here and someone uses a tissue sprayed with Lavendar ( a known calming scent, vanilla too) to smell when they are anxious. It may help to have something like that at work? I hope you feel better as the work days go by. It always kinda somber coming back from vacay.Reality and bills and all that you know? Anyway take care
