Why do shots make me feel so sick when i get them think about them ect...?

i was at the doctor like a week ago and my mom got a shot
i saw the doctor holding it and i got a sick feeling like quizey (sp??)

it wasent even me getting the shot
and when i try going to sleep it feels like im getting a shot or some weird feeling
this always happens everything they get on my mind for like a month and its really annoying
dont think im weird or anything
i just wanna know why
i like feel sick right now typing this question

it also happens when i think about blood veins cells..
ect..

3 weeks ago
pretty much all things that have to do with doctors and blood and stuff make me sick...
weird thing
my two favorite shows are house (drama) and scrubs(comedy)
both doctor shows
hahaha

sounds like you have a problem with needles.
it's a mental thing, and i rarely encountered a patient who isn't put off by needles.
don't worry, it's normal.
if you were all for them and wanted to get stuck, i'd be worried
