tw/ lab procedures, needles

hi, i just got home from getting my blood drawn and i wanted to ask if what i experienced is an anxiety symptom or something else. i have thinner veins and am kinda used to them having a hard time finding the right veins. the girl tried about 3 times and i could feel myself havibg difficulty breathing a bit as i could feel the needle moving but by the time i got out of the chair, i was a bit dizzy and seeing spots. i sat down bc i still needed to wait for them to call me to pay and it got worse, i was seeing very bright spots and feeling like i was gonna faint. they called me and while i was standing, i literally thought i could just collapse, my hearing felt a little like i was underwater and the bright spots got worse. when i got into my car it all disappeared very quickly though.

does anyone know if i should be worried?
