familiarity?

It's happening again. You're always tired from your mind going a million miles a minute. All that really appeals to you is cowering under covers and sleeping off all your relentless, pointless efforts in trying to make everything better. You are disillusioned. Maybe you know that you can change things around, but you question whether you want to or not. Because being sad has some kind of comfort to you - because there's always that familiarity. No matter how long your sadness has been prolonged, it's known that when you revisit it, the same thoughts, feeling and actions all take place. You revisit the same place where you left off.
