Frustrated

I am feeling so frustrated.  I am trying to get my blood sugars in tight control for pregnancy, but I feel so frustrated by the after meal numbers that keep shooting up no matter how much insulin I take.  I took the insulin a good 30 mins before eating too.  I thought I had things figured out, but apparently not.

As soon as I see that little arrow pointing upward on my Dexcom I start feeling stressed and discouraged.

Any advice or encouraging words?
