Update on what's happening now

so i screwed up a lot. so i freaking took my friend's ex-bf because he likes me a lot. I took her ex because i thought she moved on from him and she even likes another guy anyway. I accepted her ex bf because i didn't wanna hurt his feelings by rejecting him you know. I literally now lose the only friend i had in this world. I'm literally the worst friend possible to have. I freaking betrayed & backstabbed my one and only friend i had and now she's gone all thanks to me. I wish i can just kill myself . What did i do to deserve to live in this world ? A lot of people want me to die anyway . I'm not a good person to anyone. I honestly should kill myself why am i even still living in this world ? I'm already suffering from depression because of family issues and my friend was the only one who can make me feel so happy and i screwed it up . Everything is my fault in this world. I should die :D
