When I first began college, I had some doubt, due to the fact that I started high school with a 2.0GPA. It was not until I read Ben Carson's "Gifted Hands" that I began taking school seriously. From that point on, I began making 3.5 or higher until graduation. I graduated with a 3.2. I remember wanting to take joint enrollment classes and my mother telling me that she was scared that I would fail them. I REALLY wanted to prove her wrong, it seemed as if she had no faith in me. The one person you really want to believe in you is your mother, but I didn't feel like she believed. So, I graduated and made it my personal goal to prove to her that I would do extremely well in college. I began doing so well that she had no choice but to see that I was and am serious about my goal. If someone doubting you will help you to motivate yourself, then "let your haters be your motivators." Let those people push you to strive hard because in the end, they WILL be looking up to you. They then will realize that they were simply a stepping stone, put in place by God for you to overcome. So, be encouraged and know that you are not alone. There are others who have faced that fear and quite a few of them are already physicians.
