I am having similar problems at work with a colleague who snacks loudly all day, sings at the top of her voice and taps her feet. I’ve had whistling also from her – I agree probably the most piercing, shrill of all the noises. I really understand how sad and stressed this is making you.
Are you able to try noise cancelling earphones or earplugs at work? I am looking for suggestions for ones that limit annoying noises whilst allowing people still to communicate with you? might not be possible.
Another thought, could you say that you have tinnitus and whistling triggers a painful bout? I can’t imagine anyone will be very sympathetic about misophonia (from experience) but as tinnitus is seen as more ‘medical’ and ‘physically afflicting’ – you could say this? it’s a lie but your priority has to be your well being.
awful stupid inconsiderate people. So unfair.
