Is it just me??

Hi all! This may seem like a silly topic, but I am curious if anyone else has had the same experience. I am a pre-nursing student and we had a blood drive at our college yesterday. I had never given blood before, but always wanted to do it. I was nervous, as I always am when it comes to someone sticking needles in me. On the first stick, my vein blows. I agree to a second try on the other arm with success. I am fine, until it's over and then I feel woozy.

I finally get to the table with drinks/snacks, still not feeling the greatest. I'm chatting with a girl next to me, who had just donated too, and she starts to have a bad reaction and pass out. I get up and out of the way so the staff can help her. I felt helpless not being able to help her with the way I was feeling. She ended up being fine after a few minutes, thankfully.

Afterwards, I felt like 'I am going to school to be a nurse, and I couldn't even help this girl who was in distress next to me?' I'm sure it was just that I was feeling like I was going to pass out. I just felt like I failed to step up to the plate...has this ever happened to anyone else? I guess I just need reassurance that I'm not crazy.
