Day 13 : Simply over worked?

Well all my post seem to repetitive so straight up 7-12 work , 1-2 gym (shoulder workout) , 430-530 power lifting class (complete body workout) , 7-8 boxing class , 9 -10 hatha class , after boxing class I started experiencing some chest pain , not dure if my chest is just sore or if my heart is over worked, I was unable to stay awake for final savasana and ended up being the first one out in fear just sleeping for a solid 30min , anyways practice is right on track , must sleep soon to make 6 am boxing , be the change!
