Hyperventilation

Help.  Calling a mountain bike therapist.  Someone needs to teach me positive visualization.  Sure I burn calories on the mountain bike but only because of sheer terror.  Even the smallest dip evokes images of limbs flying, bruises, lacerations, and broken bones.  If the trail narrows or a slope appears next to it, I'm sure I will soon be sailing off the edge.  The adrenaline rush starts, the brakes go on, the limbs get weak and shakey and it's all over.  I'm a mess.  Pathetic.  New mountian bike comes in tomorrow, and, at this rate, it's going to stay nice and shiney for a long time.
