Yes at the very worst moment when I had nothing to do and when I felt I have no reason for existence I cried loud until my face turned red. I asked God that why did he created me and made me such a waste and now he see me cry. Suddenly he appeared then showed me a glimpse that how my friends would miss me when I'm not there. How they would be happy without me. How would my parent's be happy without me. And the girl who always wants to be with me. Then god told me this, "The reason for existence of people is for the goodness of other people" and he disappeared. Now I understand everything. Yes everyone those who love you always love your existence. They would be sad if you are not well. And they really really love you more than you do. So don't lose hope anytime. Be strong.
