Dr. & nurse scolded me for not doing glucose test

29w and I recently went for my 3rd trimester labs and declined to do the glucose test. I'll admit some of my reasons are petty. I really don't feel comfortable just sitting at the hospital for an hour whether it be inside or in my car. I also am super afraid of throwing up and failing. The day I went I tried fasting before I went but being anemic has been giving me other symptoms and more or less I was just nauseous already that day from needing to eat and really didn't want to risk it. I understand you can eat beforehand but I don't want to skew results. Personally GD wouldn't change much for me as I'm still going to eat what I want, so they would have to give me medication if I did have it. I've been testing my fasting sugars at home and they've been well within the normal range they're supposed to be in. Also there doesn't seem to be real serious high risk if I do let it go "untreated". My BP is normal as well and baby measures big but she's been measuring big the whole time, nothing crazy but she is big. Needless to say I was put off by my nurse and Dr both scolding me basically for not doing it telling me it "can't be avoided". Needless to say I'm thinking about just declining the test all together at this point. Has anyone else declined the test? My Dr seems set on me doing it even though I'm perfectly okay with pricking my fingers everyday if I have to.

EDIT: I don't get all the hate and negativity on here for people making decisions that aren't just doing what a doctor says. The comments they made were rude and out of line tbh and I've been testing my sugar at home so I don't understand why thats not good enough.
