I was 17 years old, working at the public library in my little town. I made a small little noise and shrugged it off thinking it was a hiccup or something. However, I continued to make this noise day after day. Then multiple times per day. Eventually, the noises evolved and changed, taking on a personality of their own.
At the age of 24 I was diagnosed with Tourette Syndrome. I had fun with my noises, and now that they had a diagnosis, I also gave them a name. They were now known as Jess. They noises had a personality of their own and we get along quite well.
