Hi BT, I just wanted to offer my condolences about your good friend. OCD is unbelievably cruel. I am so sorry to hear that it claimed a good person.
About disability dolls in the USA, I am American and I have seen them over here once in a while. Usually, if it seems like the manufacturer put them out as a joke, there will be a complaint issued through the press or Internet by any charity who works with that illness or injury, and a lot of debate among the consumers. There was once some teddy bear maker who made a bear in a straitjacket to be launched in time for Halloween. The National Alliance for the Mentally Ill put out a complaint when that happened. At the same time, there are some humorous campaigns out there for breast cancer designed by the actual women who survived it, and those get mixed reviews, too.
We have this one small company over here run by a lady who makes baby dolls with Down syndrome, not as a joke, but as an educational aid for children and their teachers. They are accurate and have typical Down's features, and come in boy and girl dolls of several races.
As for me, I used to be very hurt and angry at things like the OCD doll, but see the humor in it today. My feelings just changed over the years; I don't even know why. I started to see my condition differently in order to get myself through the hardest times. Sometimes, dark humor can be a kind of safety valve when taking it seriously is too overwhelming, IMO.
