When I am faced with a stressful situation I always reflect back to my days in high school. If I had an assignment due that I put off or an exam I didn't prepare for, the stress and anxiety was overwhelming. But I always got through.
These are all just moments in time. They hopefully teach us about ourselves and how to better cope ( learned not to procrastinate). Tomorrow will come. The clouds will lift. The sun will shine.
Drinking will never make it better. It only prolongs the stress and misery.
Write things down and choose how to best handle them and make action.
