A nurse drew 3 blood samples on 17.02 at 12:00 pm. my blood pressure dropped and i felt light headed. she had me elevate my legs until i was feeling better. i've since been feeling constantly hungry, followed by dizziness and short, mild headaches.

You fainted: What you describe is a common event for some with blood drawing. They faint as the BP drops & blood pools in your lower body. You recover, but you likely feel anxious about the event. I wouldn't waste time in worry as this is common & does not mean anything terrible. Your anxiety is likely triggering stress hormones that trigger your appetite. It should pass in time.
