failed 3 hour glucose test

I'm so stressed out now. Failed my 3 hour glucose test. Was instructed to buy a meter, strips, lancets....yada yada yada. My appointment isn't for 2 weeks so they said just eat normally and don't worry about my sugars until I see them. I work in healthcare and see people going blind everyday from diabetes, people who loose legs, feet, toes...how in the hell am I supposed to not worry about what I eat. Then the lady says being stressed is just as bad as eating an ice cream cone. My job is very high stress! I am not a sweet eater at all...I can walk by a cake, candy, soda, it doesn't even appeal to me. I haven't been taking in mamy carbs eithet just because of my food adversions from being pregnant, so I am worried if I have to cut anything out, I don't know what I would get rid of?!?! Anyone else have their doctors office just leave them in the dark like this???
