Wow, and I though my parents were whack. Tell your parents that you are tired living in their facist police state of a house, and the reason your heart beat goes up is because they are screwing with your life, liberty, and pursuit of happiness.

All joking aside, whomever suggested sativas is steering you down the wrong road. It's like weedadidas said, you need an indica based strain, preferalbly one flowered till the trichs are amber. If your heart rate still doesnt go down, i'd suggest you get a pair of running shoes...tell em you just went running, dont want to wind up obese like the rest of america.

Good luck
