Yes, it is very normal. In fact, awakening is impossible without fear, leave alone enlightenment. Fear is normal, fear is good.

You can’t overcome fear, it’s impossible. Overcoming fear is simply suppressing it, telling yourself you will be brave. The only thing you can do is surrender to the fear. No one has ever died of fear.

If things become really tough, just look at your body. Your body is fine. You can move it if you want to. You always know it on some level. All of this only goes on in the mind. Don’t do anything stupid to your body, and you’ll be fine. The body will take care of itself if you let it. When hungry, eat.
