Why do I over-yse eeeverything!?

Help, I dunno what to do, every time I'm given a task, I break it down into innumerable chunks and sort them by reasons and logic. Like I'll think about what the purpose of each stage of the task is, and it's fine but I get worn out and find it hard to talk to people when I talk so much about practically nothing and get excited by things that other people aren't paying attention to. And yeah it started years ago when parents and teachers used to force me to change myself, I would yse the problem and try and find a solution, but now that the ysing has become the problem, I'm going in circles... How do I stop over-ysing and start being a normal human being?
