Gestational diabetes...

So my last pregnancy with my son I developed gestational diabetes nearing the third trimester, this pregnancy I've been diagnosed at 5 weeks 3 days along! This has seriously put a damper on my excitement of being pregnant because I know how long these 9 months will be and I'm sure I will end up insulin dependant this time because last time It didn't matter what I did or ate, I just couldn't control my sugars... Anyone have any tips, tricks, or food recommendations they would like to share it would greatly be appreciated.
