How to deal with it.i am from delhi india and 24 year old guy

It's not the fear itself that is stopping you, but fear in general. If you got over your fear of fighting, you'd be afraid of something else, like the car blowing up. You have high anxiety and maybe panic. Go to the dr and get some happy pills. It's nothing to be ashamed of.
