Stop and observe your breath
Take a few minutes (even just 5-10) to sit in silence and focus solely on your breath as you inhale and exhale. This is a simple way to calm your mind and body and can help shift your focus to the present moment and give your mind a rest from negative thoughts. It may take some practice, so don't beat yourself up if you catch your mind wandering—noticing when this happens is actually a great sign. All you have to do is refocus and keep going, which is a skill in itself.
