Contamination: if you recovered how? I’m feeling hopeless

Mine is mostly around fear of contamination, particularly germs from raw meats and fecal germs. I’ve had c diff in the past to add real life experience to this and that triggered my ocd. My fear of public bathrooms and even using my own toilet in the house is ruining my life. I’d love to be back to normal! Or as close to. I was ok until I got pregnant during covid and got ocd about contamination with germs and covid incase it killed me or my baby, and then c diff moved the fear on to fear of getting sick with stomach bugs
