Most of time fear only come once we experienced of it and suffered from badly. Like ones we were going in car and one drunk driver hit his truck to our car. Its good that we are all safe and nothing happened to us but that accident was still in my mind so still sometime i fear to go in highway because i fear from others who drive roughly. Sometimes fear is good that we didnt make same mistake again but its really hard to face it again to remove fear.
If we face it, we will get over it. Accidents happen with everyone, but doesn't mean we stop going outside or fear from driving. We just have to be careful while driving.
Yes if we face it again and again then we can over it. But it takes time to recover. Though its about before 6 or 7 years but some how it comes again in front of mind because its terrible and we not want that it happen again. Actually it happened due to other mistake that truck driver driving when he was drunk and hit our car.
