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.
