I suffer from Misophonia, meaning that certain sounds cause me to experience irrational irritability, anger, frustration and nausea. My trigger is the sound of people eating or drinking.
Often my boss will sit next to and work with me, and often he will be eating his lunch at the same time in close proximity to me which I find unbearable.
How do I professionally request him sit away from me while he eats? Can I expect empathy from someone who is unaware of my condition?
