I have to get a blood test tommorrow but?

my doctor told me not to eat anything or drink anything except water after 12am. my question is wouldn't that make me really weak if i got a blood test and skipped breakfast and shouldnt you eat something? im kind of really scared because i hate needles and getting blood tests, i usually throw up b/c im so nervous and don't stay calm enough. i can't watch people take blood out of my arm without feeling lightheaded. i passed out once and i usually almost cry. and im 16! my other question is how do i get over this fear? im nervous about it right now and i dont know what to do b/c my doctor says if im not scared then i shouldnt throw up. i dont know what to do to not be scared though =( can someone help?

I just got a blood test too, and don't worry its not that bad. I am SOOOOO afraid of needles, the best thing to do is not look at it. If your doctor told you not to eat then you shouldn't, its so that what you eat doesn't mess up your test results. drink LOTS of water, i made a huge mistake my not drinking enough and they had to stick me with the needle 4 TIMES because they could not get any blood out!!!!! yeah i have a hard time getting my blood taken, i scream and cry and every thing and I'm 14 LOL. but my mom found this really good numbing cream it REALLY helps with the pain, it's called emla, my mom got it on E-bay for like 20$.but it was SO worth it! after i put that cream on i could not feel the needle AT ALL!!! but tell your doctor to use a butterfly needle, they are really small, and don't hurt as much ;-). well i hope it all goes well for you! and drink LOTS OF WATER, lol trust me it really helps!!!!!
Reply:I don't think anyone likes needles, but it's one of those necessary evils. You won't be all that weak if you don't eat breakfast, you can eat as soon as you leave the doctor. And if you haven't eaten anything, then there won't be anything to throw up. I would highly suggest that you drink alot of water the day before. It makes it easier for them to get blood from you. Trust me on this, been there many times. This is so true!! Drink lotz of water. It makes it easier on you too. The thing is, it only takes a few minutes. Don't watch them, in fact ask them if you can lay down while they do it.
Reply:I always take something with me to eat. Like peanut butter crackers or something handy to eat right after the draw.

Reply:they will ask you to fasten 12 hours before a blood test so that the test reads accurate they can actually see the right readings .Because if you eat durning the test the test will come false and give false readings so now they will see your cbc your tsh if your a female your esg if your a male your psh and high or low levels such as tlh tsh and zinc and acg meaning kidney and liver fuction test
