Have you heard of diagust-based contamination OCD?
I get clients with contamination OCD who are really frustrated and even ashamed of not understanding WHY they feel so unable to challenge their compulsions.
Contamination OCD that is based on disgust focuses on the idea of feeling permanently contaminated in some way.
This may be physically contaminated but can also be about being mentally contaminated. It can be themselves being contaminated, or not feeling safe in their space that may feel this way.
To work with this form of OCD, erp needs to be adapted so that it isn't just habituating to anxiety, but reducing sensitivity to disgust.
This can take longer than anxiety-based exposures because of the strong physiological reaction and often needs other techniques alongside the traditional erp.
