Hi & Welcome.
I have gone through your history and I can understand your concerns.
At the outset I would say there's nothing to worry.
Most bats don not have
rabies. For example, even among bats submitted for rabies testing because they could be captured, were obviously weak or sick, or unable to fly, or had been captured by a cat, only about 6% had rabies.
People can t get rabies just from seeing a bat in an abandoned building, caves, at summer camp, or from a distance while it is flying.
In addition, people can not get rabies from having contact with bat guano (feces), blood, or urine, or from touching a bat on its fur.
Since one and a half year has passed since you were accidentally exposed to the flying bat without actual being bitten, it is not possible that you might have acquired the infection.
Meanwhile, I recommend you to
consult a psychiatrist for proper treatment of
OCD.
Hope I tried my best to convince.
Best regards!
