I don't know what changes occurred so that I changed. Yes, I have changed. Because when I was a little kid, I used to be happy, used to have fun, studied good (lightly not stressfully), everything was going on well..inside me and around me. But as the time passed, some things changed..around me and inside me. By time many things changed in me, but the surrounding is normal and I am not.Also, I am unable to find out why this negative changes took place inside me. A person who used to be light in the past, is now full of much stress, which is nothing but created by me only and in my own head. As other things except me is normal..and for others, I am also fine. But, for me, I am completely...
