You'll probably always have a healthy respect for what can go wrong, how fast it can happen, and how it's too late to do anything by then. That's a good thing!
Not sure why you feel you might crash if you brake too much. In corners? Try to brake before you get to them, try to do all your braking while still upright, and if you need to by all means drag the rear brake through the corner.
