I feel this so much! I just got into an argument with my sister when I accidently snapped at her keyboard tapping. And then it ended up with her going back to her room to study. And it’s SOOOO frustrating because I’d love to share the room with her but my brain just snaps into overdrive as soon as I hear the sound and I can’t stop it. I’ve also explained to my family over the years what it is but they don’t seem to give me much wriggle room with how I react even tho I can barely control it. Apparently I need to grow up and let people live and I see where they are coming from but chewing noises are the worst and I often eat in my room to avoid conflict. I really hope that misophonia gets looked into more, but for now seeing I’m not alone is enough
