According to Osho, yes—one can become over-addicted to catharsis. The mind loves extremes, and overdoing even helpful practices turns them harmful, leaving you exhausted rather than renewed. The key is conscious balance: stop short of the limit, as with eating three-quarters full. In meditation, end catharsis when vitality drops or heaviness appears, staying in the middle where awareness deepens and the mind subsides.
Yes—if you push release too far, it drains you; listen to your energy and stop before you feel spent.
