Fear is the thing with which we born. Fear is literally a good thing, like fear of losing our life compel us to protect ourselves. The fear of losing a beloved one compel us to perform our duties propely towards him/her. Fear of Lord compel us to avoid evilness and infidelity. Fear of hell compel us to do good deeds.

But this fear become bad at that condition when it imposes on you or you impose it on yourself. So, Do not afraid from anyone except Lord, you'll becomr God-fearing.
