Thought stutter

Thought stutter I'm not sure which sub to post this in. I have this issue, where my brain will just shut down. I will be thinking to myself, and my brain will start stuttering in my head. Eventually it will just shut down and I will just have to move my thoughts on to a different topic. Has anyone else encountered this? I've always had this issue, but growing up I would just engage the stutter and let it go on and on until it finally "clicked". But recently, maybe a couple years ago, I realized how annoying it is, and tried to obstruct it. That's when it started shutting down.
