I need advice please on leaving the scene

What is the name of your state Nevada)?
I was in an early morning accident going to work. I was driving an uninsured car that I had not registered and had no license. yes I know it was dumb.
NO one was hurt! I got out and the other driver said everyone was ok. Thank god, but I got scared and I ran. I know I need to turn myself in.
I do have prior misdemeanors from 93, but have done well since and I do go to AA meetings. What advice can anyone give me.

You need to speak with a local lawyer. It's not clear in your post, do you have a valid driver's license? Since the car was not insured or registered whose license plate was on the car?

Good luck
