My greatest fear is God. I fear from God very much. Every other thing in this world can create panic and fear for you but these are worldly fears. For example you see a lion and you will definitely be frightened. It is natural. Some fear from heights. Anyone who will see the height first time will have some amount of fear in his heart.
Fearing from God means that you would abide by the laws of God. You will speak truth, never betray anyone, you will be honest, trustworthy and you always give charity to the poor and have a humane heart.
God is your creator and the creator of all the universe so why fear the things which he has created. We must only fear God and not anything else.
My greatest fear is the loss. Loss of time, loss of life and loss of love..., it's a very painful experience to go through loss, but it also makes us become more stronger to face the life in the future, and life just circulates between loss and pain and recovery...
I have a fear of driving..not driving myself, but when I am with other people. I actually have panic attacks and get sick to my stomach. I have tried OTC remedies with no help. I even will change my plans if I know I have to be in the car with someone else. It's embarrassing to tell people because they usually don't understand. If there is not a lot of traffic, I'm not as stressed. I have thought of seeking counseling but don't know how they could help.
I've started to notice this about myself, too. I am not as comfortable driving as I used to be. It's not as extreme as what you're describing, but I feel uneasy driving at night or in unfamiliar areas or with people in the car.
