dizzy

Today I went for medical check-up and a stupid thing happened to me.
The doctor needs to get some blood sample from me, and thus the needle is brought to my vein. The needle itself is not that painful, but the moment he started drawing blood, my entire body feels like life is sucked away from me.
Whole body very very cold, followed by horrible dizziness, almost wanted to throw up.
Literally collapsed onto the bed after taking height and weights (I'm 1.79 m weighing 63 kg btw)
While lying down my heart feels weird, as though it's dying and yet trying to beat. and yes my chest hurts, and I feel dam weak now.
Urgh, next time if you want to kidnap me, just go draw some blood from my body, then I would immediately collapse on the spot, dun even need to use chloroform.
Now I get what the dota heroes felt when pugna ultied them..
