I have had Misophonia Disorder since I was a teenager. It’s possible I had it before then and didn’t realize it. I didn’t know until decades later that what I was experiencing even had a name. In fact, I just realized that the term Misophonia wasn’t even being used until the year 2000… but I had it long before that.
The crazy thing about it is I am experiencing the symptoms right now as I’m writing this article!
