Before jumping on medication, maybe try some therapy to teach you how to cope with this
fear and learn some relaxation techniques. I had this
fear until I had my first child, and then I had to face this, and not be scared to keep him from being scared. For awhile I was terrified, but he never knew it, next thing I knew, no fear. So long as you're indoors your fine, and even outdoors chances of being hit by lightning are so small.
