(Concern) I have become extremely sensitive to noise.

I have an employee at work whom I dislike, and I have been working with that employee for about three months.

Ever since I had a falling out with that person, everything seems like a thorn in my side.

Coughing with phlegm once a minute, and the voice is also extremely, extremely loud...

So, my hearing has become extremely sensitive.

When it's nothing, strangers or loved ones may make similar noises.

I unconsciously made a grimace.

I should, but even if I promise myself, I find it hard to do.

Is this auditory hypersensitivity? Misophonia? Is that right? I think there's a mental issue.

Even if you search for solutions, blocking the cause is the best way.

Is there no other way but to separate from that employee?
