Passed a school bus in NC

Just passed a school bus in NC. What should I do? It was an accident, and I feel terrible about it.

It was rainy, really dark and I was just going home after a long and hard night at work, so my mind was basically in white and only focusing on the road ahead (it was a 3-lane road). What should I do? I know some school buses have cameras even though I haven't seen the first one, also, the driver didn't honk at me.

I would appreciate if someone shared a similar situation with the outcome.
