I always knew my phobia began when my brother as a baby had a problem that made him projectile v*. I was only 6 at the time. I did not remember, however, that I went with my parents to the hospital and upon leaving they forgot about me for about 5 minutes and I was left in the hospital with a nurse. My parents said I was extremely upset over that. I thought they had left me for good. I wonder if that is an underlying cause of my phobia.
