A good way to relax and learn to use your legs is to lie on the ground and have people walk toward you. at first place your foot on their leg and allow the leg to move and as you relax you will feel where the opening is and redirect them away from your body. Progress to do this from different stations like on your back, on your stomach and half up. Breathe and remember not to depend on your location as a distance from other people but as you are in space.
