Why am I facing difficulty in studying?

Hi doctor,

I am a medical intern. I understand that as a doctor and fellow senior you would understand the amount of social and economic pressure we are in. I was a good and a bright student. My success and fame came easy in school and entrance. Till now I have not faced failure. But, the fear of failure always haunted me and spurred me to perform. Since I have gone to medical college, I have dropped out of my focus. I cannot focus on studies or any important work. I know that I am wasting time, but I cannot stop procrastinating. I just push deadlines and always worry about the result. I always go to my friend room to see if he is reading or not. If he is not, then I am happy. I become happy by seeing his failure to read, but I do not feel that I should myself read for my satisfaction. I am always concerned about what others doing. I try to read, but wander away into browsing and then repent the waste of my time. I know that I am a good student and if I read I can do better than the average. But, I cannot read. I open a book and I just cannot go further. All negative thoughts about how much time I have wasted and how my friends are more studious than me fill my mind. I have everything including my family support. But, I just cannot be happy and study. The thoughts of failure always haunt me. I cannot stop myself from wasting time. I would be really obliged if you would help me. Thank you.
