Anyone know what its like?

its a terrible feeling to be alone... worse to know that you havent done anything right ever.... i have no identity, thought about finding a hobby, but i cant stick with anything for more than a day.. i am uniteresting, selfish, akward and unattractive.... had this been a few hundred years ago, id already be dead, only in this modern age are the weak able to survive.... but why, what am i? nothing.... i am nobody.... if im gone tomorrow, what would it affect?
