I'm pretty sure everybody is annoyed by most of these things. While I totally understand that Misphonia is a real thing, I doubt that OP really has it.
First of all, the video posted in the OP is a sensationalist news story, and it should be taken with a grain of salt.
Let's look at how OP responds to sounds that annoy him:
What you don't seem to be understanding is that this is not just being extra-annoyed at sounds and people. It literally and physically irks me. It's not exactly pain, but it comes with a physical feeling. My shoulders twitch sometimes when I'm triggered and annoyance alone doesn't do that
and compare it to how a person who actually has Misophonia responds:
http://misophonia.info/symptoms-and-triggers/The response has been described as a reflexive emotional flood of rage and panic with a storm of fight-or-flight reactions becoming paramount. Adrenaline flooding, face flushing, heart-pounding and/or shaking and the need to physically flee or attack are often experienced. The mindful thoughts that the emotional reflex/response is unreasonable given the facts of the stimulus is often actually harmless come only after the fight-or-flight response is in full force and the affected person may find themselves in a constant mode of “talking themselves down” into a normal state of calm.
They don't seem anything alike to me.
How OP describes it sounds exactly like the description of being annoyed, which everyone experiences. It appears that people with Misophonia are not just annoyed, that actually have a panic attack or mental breakdown.
