Suggest your ball busting partner get a new partner. That will relieve his stress, and consequently, perhaps, yours.
In the meantime, you should have your handicap re-visited by the Handicap Review Committee, and you should play in the 15 handicap league, not necessarily relieving your stress at all.
In the end, perhaps you should migrate over to the shuffleboard courts.
PS: This advice is not free: please have your opponents send me the twenty bucks.
