My housemate has this exact problem- right down to the issues with jewelry in particular. If she has to shake hands with somebody who's wearing a metal ring, she has to sort of ritualistically wipe off her hands afterwards. Metal in general seems to trigger the reaction much more strongly, so she'll have problems with loose coins but not stickers.
It's been persistent throughout her life, I understand, but exposure therapy has reduced its severity.
That is very interesting. Kind of validating, and one more bit of evidence in favor of trying exposure therapy. Thank you for sharing that.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
