Slope is a dangerous

Slope is dangerous for beginner. The speed picks up and not knowing how to brake or slow down, it is downright risky and dangerous. I keep slipping and nearly falling over. The problem is my lack of skills to control my speed or making turns. So I just accelerate very quickly toward a concrete wall. This is like seeking suicide. As I pick up speed, I begin to panick and worse since I do not know how to stop, I became an 88kgs missile. I could not think of a better way to abuse myself. Yet, I know I must conquer my fears. I think I will have to go for lessons before I seriously damaged myself.
