“How to regain feeling?”

Hello, I'm 17 years old. I lost feeling in my bladder and clitoris. I don't know when the bladder is full. I don't feel any excitement and sex drive anymore. The clitoris is no longer sensitive to stimuli, to touch. A year ago I had a feeling. I had ultrasound and blood tests performed by a gynecologist and a urologist, the results of the tests show no abnormalities. At this age, I shouldn't have any problems with it.
It worries me that I won't get any pleasure from having sex. What could be the cause? Is there any chance and way to get back feeling in clitoris and bladder?
