BP

BP  when I'm thinking about baseball - - batting practice

BP  when with my golf group - - Barry Polley

BP  when in chemistry class - - boiling point

BP  when I need gas - - British Petroleum

BP  when I worry about my health - - blood pressure

One day when I was coaching baseball, one of my players was taking BP and he reminded me of BP trying to hit a golf ball.  I reached the BP when I saw the price of gas at the local BP station and my BP got so high I thought I would have a heart attack.
