i hate this world and i feel sad

i hate hate hate my life, my self and everything in it.
i hate my friends i hate the city that i live in i hate my house i hate my body i hate my voice i hate how i cant do anything i hate my habit of making everyone around me hate me

when i told this to one of my friends she told me a lot of people have it worse than you. you shouldn't want to kill yourself because you have life better than most people. you have money, you have a house, you have clothes, you have parents. and i dont really understand it when people say this because it doesn't make sense to me. just because a person has it worse than me, i can't be sad?? it's like saying that a lot of people are happier than me so i cant be happy. if i am sad, it's purely about me. it has nothing to do with anyone else. i dont understand this world i dont i dont i dont.
