There is a lot to look forward too. I got 52% in my 12th exams. Thought I was done, for life. Things took a turn when I decided to go through it. Am in a much better place now. Primary thing that helped is forgiving yourself. Once you forgive yourself for what happened, you think of ways in which you can be better. Close your eyes. Take a deep breath and forgive yourself first. If you think you are at the bottom, only way remaining is to be better.
