Hi Silversparrow

I'm really sorry you're having a hard time with this. My doc suggested a few things that work for me that may or may not work for you.
One is scents...if at home use an oil-burner and the scent of lavender is very calming. If out and about there are little scent-filled pouches that you can carry which do the same.
Another if at home is a bath with candles and music that you find relaxing.
If out and about...it depends on you personally. Like my doc suggested a small keyring with a teddy bear coz i still find teddy bears relaxing...or a pocket size pic of something you find comforting. Also having a personal music player, mp3 etc is something i find useful coz i can play soothing music wherever i am without disturbing others.
Sorry if this has been no help to you but I know you'll get better answers.
Hang in there.
Much love and hugs to you,
roz
