I have sensory processing disorder, so I've got the whole sensitivity to sounds as well as other senses to boot! I'm very sensitive to tactile input, sounds, visual things (bright lights, flashing lights, etc), and some tastes (spice and salt to name a few). I also have the full broad spectrum of being sensitive to vestibular movement (If I lean my head backwards I get dizzy and I will also fall backwards/stumble when standing), but also craving it as well. I loove to swing and rock, and will easily spend hours in a swing just calmly swinging.

I could go more into depth but i'm already off topic as is. But honestly if you think you have misophonia, try to rule out SPD first. The two share some very similar symptoms but SPD has neurological ties to it and there's effective 'treatment' too- via Occupational therapy. Specifically the listening therapy can help with sensitivity to sounds, and probably Interactive metronome (but not sure on that one).
