The worries

Olivia • Had our son in April 2016 😍
I am having a normal pregnancy (due April 1) and yet struggling lately to keep the anxious thoughts away... The what if he isn't okay? What if my crappy diet the last couple of months  (going through a major family crisis and been eating way too much fast food and generally emotional eating too much) has hurt him or what if he gets caught in the cord and can't breathe or what if something is wrong and my doctor never noticed or what if something goes wrong in labor or well you get the idea, just the what ifs? As much as we have so much left to do before our son is born, the waiting is getting to me. I want so badly to hold him already and know he is fine. This is my first pregnancy and I assume it's normal to worry but what do I do? I don't want to be stuck with the what ifs, I want to be happy and focused on the blessing that everything seems fine. 
Do any of you get this way and how to you make yourself feel better?
