The purpose

Loneliness ? Hate ?Madness? Paranoia? Everyday I look around and see .. I wonder if it is really necessary..How can one try to have feeling knowing that is incapable of any kind of affection or expression that's considered to be good? Many times I look at myself and try to realize the meaning of my existence.. Does one need to try to live? Does one need to be social? If so..Why? as i said..not everything needs to have a meaning or a purpose... We are all just figures of imagination created by something that doesn't have anything more to do than make beings of raw meat that interact with themselves...while it watch and laugh at our attempt to become someone or something... needless to say "in vain"...

why?
