Im worried about my memories. Unlike other people they can still remember exactly the happenings, years ago. But me, i dont even remember anything unless they show me some proof like photos that i was a part of it. I dont know what happened. Even if it was just a year ago or a month ago, i can remember some of the details but not exactly. My friends just help me to remember it. Is it normal? Do i need to habe a check up already?
