I attempted yesterday and something weird happened

Yesterday I attempted. My life has never been the best, I have been SA'D, I have been abused by my parents my whole life, forced to grow up, and had tendencies since 7 when I grabbed a knife to my neck. The nail in the coffin was my bf that treated me so well getting overwhelmed because I have anxious attachment and might possibly have bpd or smthn like that. So, I attempted... I took a bunch of drugs downed it with coca cola and made a noose ish thing in my closet. For some reason, I immediately passed out as soon as my neck hit the rope... I felt like I was sleeping. The noose thing wasn't really well established so I slipped, but then I started seizing but I was still asleep until i heard a voice telling me to wake up. I woke up noticing it was my own brain telling me to wake up and blood all over because when I fell I bit my tongue really bad and prob broke my jaw. And it is infact true that u give out bodily fluids when u die, gross. Had to really take a shower and scrub. It's a really interesting experience . Im just wondering how I passed out that fast, I thought I was gonna have a struggle breathing...
