I've been diagnosed as having OCD-moderate, right now it's under control, but wasn't for many years. It's tough.
Maybe ... Everybody suffers OCD differently, but there's a chance someone else suffers it like you.
I have a Sort of slight OCD involving pain
If I feel pain on one side I NEED pain on the other side
On the other hand it also works with numbers I can never do with an odd number
Even numbers forever!
And a whole lot more!
