Potential scratch? What to do?

idk if this is the right subreddit to post in but basically im on my red p's and as i was driving to school today i may have accidentally scratched a bus?

i know its stupid that i DONT know but basically i stopped a bit to close (completely my fault i will admit that i simply didnt slow down fast enough) and the bus was only able to fit partially into the bus stop lane? sorry my explanation might be confusing but basically i tried to go around because i thought i was too close and the bus wouldnt be able to get past me as it exits. There was still room in my lane as it was a fairly wide road and i drive a very small car so i simply went around (didnt change lanes because again, there was enough room in my lane to do so) however my friend who was in the passenger seat thinks i may have accidentally scratched the bus with my mirror as i passed it

i personally didnt notice this and didnt even assumed anything happened until we parked and my friend asked me what im going to do about it. i assume, with my friend in the passenger seat she would be more credible than me but i truly don't believe the vehicles made any contact and i feel like i wouldve noticed/heard if they did, even if very lightly - there's also no damage to my car where it wouldve touched the bus

assuming i did scratch the bus and in result drove off (as i was completely unaware) would that count as a hit and run? And what's the best thing to do now?

I understand this might make me sound entirely reckless but this is the first time anything like this has happened, i understand if ur gonna judge me for this but i would appreciate genuine advice as im currently stressing out during my classes and cant find any advice for my situation anywhere else
