I was going through some personal problems a year back and found myself constantly just staying up into the night, playing game after game of 5/0 or 3/2 blitz chess. I couldn't stop. It was therapeutic, but also a way of sort of avoiding the problems I had going in my life. I know it wasnt the best use of my time, but man it felt good to tune out for a while and in a weird way I think it helped me get through some of the problems I was facing.
