Just diagnosed

I’m 25w1d and was just diagnosed yesterday. I feel so defeated by this like why me when no one else I know has ever had to deal with this. I feel so frustrated because it was so hard to get pregnant and now that I am I feel like everything is going wrong that can go wrong. I know this isn’t the end all be all but I just feel soooo defeated by it. I mean I’m supposed to eat ice cream when I want to and eat whatever I want I’m pregnant but now I have to be so strict and worry about the baby and getting actually diabetes after pregnancy.
