You can train your nervous system to be more resilient to stress and anxiety by practicing mindfulness daily for a few minutes.  The key is to practice daily, even if only for a minute or two.  Try to find several practices you enjoy and cycle through them. Or if you need help structuring your practice, get started with a program.
