Threw myself head first into 80+ hour weeks of work, career climbing etc to avoid dealing with issues (incl. some trauma) I had since childhood. Told myself I'd be "married to my work", because while people leave you, money lasts longer. Gained some modest success, but woke up after 5+ years to the realisation that no matter how much I worked, none of the success, money or appreciation from peers would ever feel whatever void/emotional avoidance I had inside and was trying to mask by marrying myself to my work. By this time, I had a severe eating disorder and probably some sort of severe burnout.
