Isolating yourself from social contact is a pretty common response to feeling unhappy, but there’s a large body of research that says it’s the worst thing you can do. This is a huge mistake, as socializing, even when you don’t enjoy it, is great for your mood. We all have those days when we just want to pull the covers over our heads and refuse to talk to anybody, but the moment this becomes a tendency, it destroys your mood. Recognize that when unhappiness is making you antisocial, you need to force yourself to get out there and mingle. You’ll notice the difference right away.
