3 hour Glucose test

Has anyone not passed the 1 hour test and then passed the 3 hour test. My doctors office just called and I have to go back to do the 3 hour test. I’m so nervous and scared. I felt awful the whole time for the 1 hour not because of the taste of the drink but from not eating so long before and then for the test. I felt dizzy and faint and just horrible the whole hour and after until I got to eat a real meal and took a nap. I’m also hoping that I pass the 3 hour one because I’m just a ball of nerves for what all of this could mean.
