Accidental overdose

The other night i went to see a movie that strangely resembled myself...or who i once was. it disturbed me. And i was shaking the whole ride home as my friends discussed how amazing the film was. I dropped all of them off at home except one. It was 3 am. I started crying. He insisted we stop and talk about what was up. So...i did. We talked. I dropped him off. I went home. It as 4 am. Mom screamed at me for coming home so late. i had no food in my stomach accept some sushi i ate at 2 that afternoon. I drank some nyquil i had just bought to fall asleep. She yelled at me. I drank some more nyquil ontop of the excedrin and ibuprofen i had taken to get rid of a head ache. Eventually i drank almost the entire bottle. I was antsy. I just wanted to sleep and get rid of all the thoughts in my head. My ankle kept twitching and i wanted it to stop.
I didn't mean to overdose. I didn't even realize thats what i was doing. I just wanted to sleep. i wanted to sleep so badly. I woke up in horrible screaming pain with my head in toilet full of blood and stomach acid. Screaming. I really did feel like i was gonna die. My mom came up. I forget the rest. I woke up in the morning. Repeated the same thing with my head in the toilet and lying on the ground unable to move...but i can remember this part. My mom came in and said "your lucky your sick or i'd be really mad."
My family made fun of how funny i sound when i vomit. No one knows it was an overdose. I was completely delirious and no body noticed. I don't even remember my mom taking care of me i just remember her presence.
That afternoon (or what felt like the morning when i could finally get out of bed) i realized what i'd done. I looked up levels of whats a lethal dose of acetominophen. i had enough in my system. I didn't mean to do that. It's like my subconcious tried to kill me. Logically i know not to keep drinking nyquil to fall asleep. I just...kept thinking i wanna sleep...at any cost i guess. I kinda wonder what would've happened if i died. I still haven't told anyone about it...and i won't for a long time. It's just... even when I'm literally dieing infront of someone...they are laughing at me.

Thank you. a lot of what you said rings very true but i do think our situations are different. I know my family loves me. They are just blind. but...i really appreciate just the fact that someone read this and someone responded. Usually, not trying to sound melodramatic, but i can be balling my eyes out and no one sees me somehow. Sometimes i'm hiding it...but sometimes i'm not and at those times...it's nice when someone actually responds. thank you.
