Positive vibes please

Hi ladies! Any words of advice on how to stay positive, hopeful and not (too) anxious with a pregnancy after loss? I lost baby #2 in October at 21 weeks, we found out baby's kidneys had not developed properly and had to terminate. They're doing an autopsy to find out if it was for generic reasons, we may get results soon but I am already 8 weeks pregnant. How do you stay positive with a new pregnancy? I am so worried all the time and find it so hard to speak about it, I just can't let myself believe this will be all ok until i have baby in my arms 😔
