Do not project your problems and insecurities on other people in that manner as you are part of that violence so you will bring that to you by your irresponsible behavior.
You have two choices to stop fearing things in life.
1) Attain Nibbana by living simple life and following TRUE and PURE Dhamma then you will experience Niveema and Niramisa Sukha so your mind will be calm in that experience like in Nibbanic bubble.
2) Be adapted to the situation which creates fear in your so you have more control about it and over it. It does not mean that you need to be violent but responsible to the situation which coming on you. You seem to want other things to control your life or some higher power, not yourself – that where the fear comes. Rather than trying to dodge the situation try to face them.
