This may sound trite but have you tried mindfulness meditation? I'm far from an expert but my understanding is that instead of fighting or avoiding all the chaos in your mind, you sit quietly still and let the thoughts wash over you and just listen to them without judgement or opinions. Just observe what is happening.
If you get locked into a particular thought or topic, first notice it, then let it go.
It's extremely difficult to do but over time this practice of noticing builds a mental muscle and helps you focus your thoughts towards what you want when you want.
