I have this issue where when I get very busy I shut down. Then I get behind at work/life and start living in this horrible cycle of shut down - panic - shut down - panic. I've done it for years but wasn't until recently I realized it was an issue. Since then I've been searching for an answer as to why I repeat this obviously destructive habit. Trying to find the reason why my mind works in that way when it hit me, it's just that a "habit". There may not even be a reason or a cause, maybe I'm just a creature use to that particular habit. I have to stop worrying about why and start focusing on the how to stop it when it happens. Big things happening over here.
