I vomited my Glucose drink. twice!!

Love me
My obgyn asked for GD ( diabetes) blood test , Ive been to the clinic  a bunch if times and everytime they end up taking blood  for nothing cause I end up throwing up the glucose drink :( Im so angry . And today another nurse did the blood work and it looked she didnt wanted to do her job, , she didnt even search for my vein , my arm was bended and it was so fast, i can tolerate pain .. and this time I even said it hurt and she never apologized ,Now my arm hurt even when im not moving it. I wanted to tell someone and when I came back saying i threw up again, she saw me with rolling eyes  lime if it was my fault
