Gestational Diabetes...!!

Ayesha
Today I got the result for 3 hour glucose test n I failed it... Feeling so bad n disappointed.. My scores were 
78 out of 99
183 out of 179 
142 out of 154
147 out of 139
 So I cleared two of them n failed in two so she told I have GD .. 
Does anyone of you failed so badly as I did n now what are your precautions.. She told me I need to go to a dietician n than follow the diet. What you would say??
