I have this problem, where I did get rid of R.OCD and slight germophobia (hair and body fluids), which was great. When I fully let go of this and also decided to eat stuff I considered bad again, I ended up in the hospital several times and they found out I have several severe allergies for indeed the foods I avoided as I was convinced they made me sick. I also have a metabolic disease where touching certain items, breathing in the pollen or cross contamination, can get me hospitalized and even kill me. So there started my C.OCD. as all my previous worries were now confirmed instead of debunked.. I feel like this is a joke from the universe, as now (how my psychologist said it) my OCD has become an actual necessity. I know I go overboard with things because of these near death experiences however to the point I do not want to leave the house. But they are not allowed to do exposure therapy, as it can endanger my life. What would you advice?
