Are you scared or still in disbelief to be prego?

I'm pregnant with twin boys almost 16weeks . I had my daughter almost 6 years ago. I had a miscarriage in February of this year at 14 weeks he was a boy.  It feels very real being pregnant but I can't help but be so scared and feel like I'm not going to be able to make it all the way. I'm so scared of them passing . And since I heard identical twin boys have a high risk of miscarriage:( I can't imagine them in my life yet. As if something might go wrong :( I know I shouldn't think this way but it has been so long since my 6 year old and I just lost one :(
