Thank you everyone for your encouraging words, and for your advice. Means a lot!

It's true, with everything constantly going downhill, incidents like the one with the police are more than I can handle. I really hope that receipt will make them believe I have nothing to do with that, even though it's still odd that the one who reported me knew my licence plate. Also, it's strange that this person has obviously waited a week to report me. The entire thing is so confusing! Will keep you updated.
