Learn to ride a bike?

My mother always said to learn to ride a bike. but I was scared that if let go I would go down the wrong path, so my legs would always go backwards on the bike. yet I couldn't reverse. I never understood why I couldn't get myself to go forward. It just felt scary, so I closed my eyes and tried to go forward everytime I was let go, but I always try to go back. I didn't move even if I was trying as hard as I could. I couldn't, So I never learned how to ride a bike because I was too scared to go forward I always wanted to go back. This isn't about bikes.
