@SoVeryBritish No 2 will only work if your windows aren't blacked out, which mine are. Which I forget on a regular basis and still proceed to do no 2 (not the wave out the window)
@AnthonyJBurt Exposure therapy for someone with Misophonia has been proven to compound the situation. It just doesn't work. There are steps I can take to help. Earplugs can really help. Unfortunately visual things can also trigger me. I hate it because it makes me on edge all the time.
