venting and advice I guess

7weeks pregnant and I'm so sad. My doctors just called me saying I might have gestational diabetes and need to take a 3 hour sugar test. this is my second pregnancy and I'm 24 years old. I happened to manage my sugar levels last pregnancy by diet and exercise and I'm sure I'm just emotional and it can be managed again but it's just so depressing. I just want a normal pregnancy! I love my body and my babies. I'm praying I just failed the one hour because I didn't fast for it. I don't want to be diabetic. I care for my grandma who is diabetic and watch how her organs are failing her . I just want to be normal... does anyone have any reading material or advice or something? thanks for listening to an overly emotional mama !
