I'm a normal girl. I know not everyone enjoys sports, but you also said you don't like any exercise at all. You also mentioned you don't know how to do those active things, so how about picking one and taking a class? You'll learn how to do that activity, get exercise, and meet other people who enjoy it too. Also realize any activity can be made to exert more energy. For example if you enjoy typing like this, how about typing while you're standing up, or using voice-to-text software to 'type' while walking around?! You can also dance while listening to the gospel music by bouncing and clapping your hands. Exercise is essential for a healthy mind and body, so please move your body!
