what is the point/i might be giving up

im depressed and bored and I dont want to be here anymore. my life is empty and i feel completely trapped in it. nothing fills the emptyness I feel in my heart or soul. i just want to lay down and never get up. but i keep going because im supposed to, surviving on what gives momentary satisfaction like shopping, or food or exercise or television. i hate myself and i feel worthless. i want to ask an old friend how theyve been but Im still too mad at him to do it. i want to go out somewhere but i cant. theres no where to go and no one to go with. my best friend has left me to go out with her slutty frends that im not good enough for and my sister is out at a school dance with all her friends. everyone is out and dolled up but im at home alone on saturday night in my sweats. whats the point in being alive if you're miserable the whole time?
