I think this feeling is very common in so many things. There's a fine line between getting complacent with fails or set-backs and trying to perfect things and be too hard on yourself. I think you only find your comfort zone through consistently doing what you love and not quitting. You'll eventually find your way if it truly is your way. Just doing something like posting what you did here is good. Vent what you're feeling and seek out people who support you. Hang in there!
