When you feel you're at the end of your rope, you tend to disengage from others. This may "work," but it does have a more abrupt side that upsets your health in subtle but serious ways. When you detach from others you detach from yourself. This sends ripple effects throughout your whole body. It tells your stomach its hungry even if it's not, it tells you to sleep instead of staying active, etc. Keeping an eye on yourself is key.
