Regular exercise can help to reduce stress, feelings of anxiety, and symptoms of depression while boosting self-esteem and happiness. If you find yourself fighting the urge to nap during the day or just generally feel like you’re in a fog, your body may be telling you it needs more rest. Write down how many hours of sleep you get each night and how rested you feel. Start by making one better food choice each day. Start each day by acknowledging one thing you’re grateful for. Repeat this process several times, until you start to feel yourself calm down.
