I am 19 and I have not lived

It sounds weird to say this. I am ONLY 19 and still have (hopefully not) a long life ahead of me. But I genuinely cannot remember anything. I have no favorite memories, no favorite food places, no favorite hang out spots, no nothing. I am socially nonexistent. It just hurts because whenever I’m talking with people my age and they start bringing up old experiences or adventures I just stand there and listen and just think about how miserable and mundane my life was and is going to be. It’s gotten so bad that I can only be nostalgic about music and video games. High school? Totally forgot what life was like despite me graduating not too long ago. Our old house in that tiny town? Absolutely zero recollection of what the rooms looked like. I even forgot the existence of my old bestfriend had I not stumbled into him the other day….
