When I was in college before my final exams I was not well prepared and I wanted to pass in my exams. I tried prayer and going to churches.
Since I wanted to pass at any cost so I though the devil would help me pass and I said that I want to sell my soul to the devil. I do not know how that works by saying something like that. I feel guilty for that as I have done a silly thing and I wouldn't have said it. But that too did not help me, it only makes me feel miserable.
This bother me when studying even now and I am not able to concentrate on my studies and I haven't been able to appear for my exam for this reason.
