scared about the glucose test tomorrow

i had an attempt at the glucose test 3 weeks ago and had a girl who had never (i am serious) pricked anyone with a needle before, she had finished the course the week prior and i was her guinea pig. She missed, and messed up my arm really bad. I am now terrified of needles! Am so worried ill get someone as useless as she was 😭 ...

Now also, when i tried to drink the glucose drink it made me feel super sick and i couldnt finish it in 5 minutes... got halfway through and chucked a tantrum and walked out and left. Why do i need to drink it in that time frame ? and do i really need to drink it all? cant i just bring heaps of jellybeans?? orange juice?? drink most of the stuff and not all?? is there anyway or tips on how to do this successfully? i know i might seem like a sook and youre all probably thinking get over it its a drink and 3 needles.... but..... im SO scared.
