I cut someone off on the road and I feel bad about it…

For context I was on a single road toll and I was behind this slow driver and they seemed to be either a new driver or a overly cautious driver bc they would tap their brakes to maintain a certain speed, now typically I wouldn’t care considering there isn’t much I can do about it however this time, I really needed to pee, like borderline piss my pants. So there is this section on the road where it splits between toll and HOV and then it goes back to being one road again, so I took this opportunity to get in front of the slow driver bc I REALLLYYYYY needed to pee. So I sped up and I cut them off and it wasn’t until later that I realized I should’ve hit my hazards as a apology. So now I feel about about it bc what I did was rude and it could’ve lowkey traumatized them and ik there isn’t much I can do about it now since it already passed and karma will come back at me for my actions but I just needed to vent about the incident.
