GTT is variable: A glu tolerance test is variable, which is 1 reason its not done much. It is hard to compare 2 hr post-glu with 2 hr post-pizza. If your glu were 163 post oral glu, that would be impaired glucose tolerance, which may be what you have. Probably best to focus on what you can do. If fasting glu less than 126 and a1c less than 6.5 you don't have diabetes, yet. Can you improve your exercise and weight?
