TRANS OCD - I wonder..

I wonder how many people with trans OCD are actually trans or figure out they're trans and look forward to transition when their mind is clear and the anxiety is gone (treated) again? Just curious. I know there are people who are trans and have OCD, but I doubt they have anxiety about being trans, but other OCD concerns. I've never managed to find a distribution or something. If someone who suffers from anxiety when they think of being trans and is ACTUALLY trans (I don't know if that's possible) and the number of people who suffer from trans OCD and aren't.

When will we know again or when will we be sure we are comfortable in our bodies and when will the feeling of being the opposite sex when you're not subside?
