Here are some advices:

Calm down. Chances are police would never come. All they have right now is a 911 call and a possible witness. Nothing else. They may investigate if they have nothing to do.

Consult a criminal law attorney. Normally a first visit is free. The attorney may not do anything without seeing an actual charge. You do not even know which law enforcement agency responded to the 911 call. This is just in case something would happen.

If and when the police come, do not say anything to them without your attorney presence. Do not trust the police no matter what they say. This is why you need an attorney first.

Lastly, do not do it again.
