I had a little Google and this sounded similar to what you're experiencing?

Doesnt really offer any help though! I would recommend The ACT workbook for OCD, Marisa Mazat. Been working through it with my psychologist and it is helping me. Our obsessions are different but the CBT/treatment is the same. The woman I speak to said its one of the best books to recover/live well with it. I also had a massive fear of taking medication, not because I feared allergy but I used to be obsessed with vomiting and wouldn't take any tablets. I recently managed to face that fear and start some tablets for anxiety/ocd and they're starting to kick in I think! You're not alone in your worries X
