Box breathing is a technique used to calm yourself down with a simple 4 second rotation of breathing in, holding your breath, breathing out, holding your breath, and repeating. Also know as Navy SEAL breathing technique, or tactical breathing, it's a surprisingly simple and effective way to help regain calm and control of your thoughts when under stress. A perfect visual meditation for when you can't listen to audio, or just need a quick second to refocus. Use this image to help you keep time! :) Here are the directions: Inhale for 4 seconds (as the circle expands) Hold your lungs full for 4 seconds (as the circle stays fully expanded) Exhale for 4 seconds (as the circle shrinks) Hold your lungs empty for 4 seconds (as the circle is contracted) That's it! Repeat for as many times as you need to calm down

Greetings It is absolutely necessary to understand the importance of accepting that you are going somewhere wrong. I would recommend you to understand the pattern of behavior which is triggering a fight amongst you too and try to discuss it out for yourself. Secondly you can start channelling all your energy in  journaling all the reasons you are angry with her  and mention all things you both could do differently to control your anger. Also get detailed evaluation for better management Thank you
