I would say NAY!
The word 'blood' itself scared the shit out of me, now imagine to donate some.
The reason I write about this is because something happened to one of my besties today. She decided to donate her blood for some charity work but unfortunately something bad happened, she fainted.
Few years back a former course mate of mine donated some blood and what happened to her was, she got nervous and dizzy every time she went to tall buildings,
even if it's only the first floor!
This is sooo scary !Please don't harm yourself if your body is not fit for it even though
your intention is good.
