Thank you. My sister passed out a few minutes ago all of a sudden so we were concerned for her. I think it might have been that she was in the heat. I hope it's not anything bad. My parents are soon gonna be taking her to the hospital to check up. Pray for us whoever is reading this.

Not sure if what I experienced was this but I was watching tv one night and decided to brush my teeth but the entire time my vision was fading in and out until I couldn't see anything anymore. My body and head kept falling but I still tried my best to use the wall and mirror as support. I literally rolled my body on the side of the wall and crawled my way up the stairs. I could barely feel and hear my surroundings but I still fought it because I didn't want to pass out on a floor and bang my head. I almost couldn't get up from crawling and I barely twisted the door knob and instantly collapsed on the bed. Took me 3-5 minutes to be okay again. Idk how I even did that lol. I know my vision fades for like 10-20 seconds sometimes when I stand up but this was the worst I've had.

I get blackout on a daily basis atleast once a day

[whiskeytangofoxtrot]

so today i had a college exercise exam and i pushed myself to the absolute limit and beyond for this pre-exam and i overworked to the point where afterward i couldn’t see, i could barely stand, i had very little cognitive ability and i had gone limp for a second or 2. you know when you stand up too fast and you get dizzy and your vision goes all weird yea that was me for about 10 min straight and i literally couldn’t do anything really after that for about 30 min. i am on a research spree to figure out exactly why and what even happened. if anyone is wondering what exactly i did, i did a 500 meter sprint, 30 push-ups, 10 burpies, 40 sit-ups, and 30 1 second squats. a probably big factor in this is that i hadn’t had water since about 20 hours prior.

[dsrxvlogs]

When you start blacking out....then asap you should exhale all your breath and hold breath for a few seconds until it becomes normal

[ANNIEMAHANTA]

Oftenly like on daily basis i have blackouts for several seconds that is for 30 to 45 seconds. At this moment i can't see anything nor i can stand properly moreover i hear a constant beep sound until i gain my conscious. I've told my parents they told it's normal but i don't think so it is. Can you help plz🙏🏻

What happens to me when I get a blackout
Is this..




Everything is black and theres my worst fear (like the Ocean) and i get pushed into it
And I can't breathe, even in the real world
And after 5 minutes, I wake up and it ended up being an hour of me unconscious
I never tell what happens to me when I get a blackout
Im not sure if it's a blackout or something else..
