i got blood taken this morning and i almost passed out. my vision was gone i was so dizzy and got so pale and lightheaded. i got so so nauseous i was so convinced i was gonna throw up. i felt like i was about to. after having some juice and some food i was fine. but all day ive been still not feeling well and feeling really nauseous and my stomachs been hurting. is this all just from me being so worked up about this morning??
