If you are in the medical filled and you have this, it's a roller coaster ride. I just can't remember how many times I have washed my hands when I had contamination OCD. I was hardly able to see 20 patients a day. And then the fear of contracting someone's thoughts when speaking to them.
Everyone has repressed memories. I just remembered that I felt attracted to a kid 6 years old and I was 14. I didn't do anything wrong, but the thought lingered on as to why I had such thoughts. That was once. I couldn't explain why. That is a repressed memory. What you are doing is imagining.
