Guilty Sushi lover 😢😷🍤🍱

Just know this is a bit of pity party, so bear with me.
I'm about 5w3d, I love sushi and I was told you can't eat sushi while pregnant so in the months prior I gorged on my favorite meal whenever my heart desired. After falling pregnant I did a bit of research (on the net) and found that sushi could be consumed but only certain types like shrimp, salmon. 
So against my DH's advice of checking with the Doctor first, I ate to my heart's content. And now I feel both terribly guilty and immensely ill, nauseous and on the verge of hurling my guts (but trying with all my might to keep it in.
Am I going gaga? Is it all in my head? Did I jeopardize my baby's health? I just feel awful that I couldn't sacrifice this one thing for someone so precious. 😔
