3.Meditate

Attention training is a meditation technique that can benefit people with anxiety and depression. The easiest way to practice it is to focus on something completely mundane and routine, such as washing dishes or folding laundry. “You simply direct your attention to the task in a way that may even feel hyper-focused and ‘zero in’ on observing yourself and any sensations that arise,”

That laser focus can help quiet other intrusive thoughts in your head.
