why doesn’t anybody realise?

sometimes when i get down its worse than other times, sometimes i cut more than other times sometimes i just go to my room and cry or scream until i get dizzy. but other times all i want is for somebody to notice that i’m down and give me a hug or tell me that they care about me. But nobody does. why dont they realise? nobody notices ever. i don’t want to tell anybody but if anyone i knew actually cared at all they might notice for once and ask me if i’m ok, nobody even asks, nobody understands me and i just want someone to actually care about me for once, i’m tired of caring about everybody else
