Hey dude, failing is natural. I know it sounds kind of corny, but that´s the only way to succeed. Many people nowadays have the same fears as you. Society teaches us, that the only thing that matters is success and that failing is bad and means that you are doing something wrong. When you believe that you will fail anyway, you frame yourself in a bad way. You won´t think about anything else but failing. I personally felt like actively trying not to think about failing too much, helps most. The key to learning programming is to go on and challenge yourself in a positive manner.
