Being stressed can be very challenging— we tend to miss our meals, have lack of sleep and relaxation, and don’t get to enjoy quality time with the people who matter. But, because we must continue with our daily life despite the stress, we tend to ignore the physical and mental effects of stress on our body for the sake of our goals.
Because of stress, it's possible that the nutrients in your body have started to be depleted. Overthinking may cause the vital nutrients in the brain nerves to be affected, which can cause you to lose focus and become distracted. The lack of nutrients because of overwork can make you feel more tired than usual, and you appear pale and ill which could be the source of your unhealthy skin.
