I hate life.. part 2

She drove off. i tried calling and txting her theres nothing she wants to do with me. i called her last night she called back. i said i could be friends thinking i could within 30 mins i called back. no answer so i sent a text saying sry nvm i love you too much. i have a feeling im just done with relationships. i try so hard but get no love in return. i get the feeling she never liked me and just wanted to make me happy. im getting awfully depressed and thinking of cutting or some suicidal attempt which i highly doubt i could pull off. well good day.
