How does fainting feel like?

(no idea which flair to use)

I've always wanted to know how fainting feels like. What does the world look like when you fall? What goes through your mind as you fall? How does it feel? Does it hurt anywhere?

I've been very curious. I've always wanted to faint at least once, so that maybe just maybe people will care about me, even fantasized abt getting cancer, or in a car accident, or getting hospitalised for something.

I've been extremely underweight (almost 21, 5' 2", but I don't even weigh 40 kg) I had anaemia throughout my life, only took iron supplements for the first time this year coz my anaemia became life threatening. I've been dizzy, I've starved myself, I get so nauseous if I don't eat something as soon as I wake up, I've had everything but inspite of all this, somehow I've never fainted in my life even though girls in my school would faint left and right during summers.

Yeah this became a kinda rant, sorry, but basically I just wanna know how does it feel like to faint if any of you have fainted....

Edit- Thank you very much guys for giving me a reality check and putting some sense into this stupid head of mine.
