Pregnancy Depression

So I'm 20 weeks pregnant and I just recently started feeling kind of depressed and blue. I have had 2 past miscarriages under 10 weeks before doctor found out what was wrong with me. Now I am constantly worried about this baby. I get an anxiety attacks everytime I have to get a sonogram, I'm having so much trouble controlling my sugars, it seems like if I even smell a carb my sugar spikes. I don't feel like myself and feel like I am stuck in a body that I have no control over. I want to enjoy my pregnancy and be happy and I want to be a good mother but idk what to do about how I feel. Has anyone else gone through this?
