I've lost all zest for life. I'm such a tremendous failure. I wish I could just erase myself and rid the world from one incurable  infestation. Everyone thought I was destined to become a successful person. I had high hopes for myself, I wanted to become a great writer and a data scientist, but depression has led me astray. I don't think I can write anymore. My capacity to think has dwindled. My cognitive abilities have declined. I feel almost a burden on anyone who has to deal with me. I don't think I've had a genuine laugh in the last three years. I can't talk with people, mostly because the trivialities of daily life bores me. I just want to leave everything and disappear. The last three years have been hell. The supposedly best years of my life is slipping away and I think if these are the best, how bad could it get? The first and last thought that comes to my mind is killing myself viciously. The only thing  I genuinely enjoyed was  reading literature, but haven't had the courage or energy to read in the last 3 months. I'm just 21, waiting for death to come and assuage the pain.
