Gestational Diabetes

I'm devastated. I just got a call that I failed my 3 hour glucose test and officially have a diagnosis of gestational diabetes. I've tried so hard to remain healthy. I lift weights 4 days a week, I try to watch what I eat and it feels like it was all for nothing. I know it's pretty easily controlled with diet but I'm just worried about the increased risk of diabetes later in life for my baby and I. 😔
