Fear of trying again

I was 35 weeks pregnant when I went into labor and had my baby boy via c-section, he was in the NICU and died of a brain bleed 6 days after he was born. He was my second son.

I'm so scared to try again, I'm so scared that if I get pregnant my baby will be taken away again, but I want another baby some day, I'm just so scared, I couldn't handle losing a baby again, I could barely get through losing my baby boy, but I push through for my 4 year old because he needs me. Anyone else go through something like this?
