Kinda need some comfort

I lost a pregnancy in August and am now pregnant with my rainbow baby due in September 2017. I am scared shitless of another miscarriage. We are super happy but i dont feel like i did last time because of the fear i just wish it would go away. I dont know how to cope with the anxiety except to pretend im not freaked at all. I dont prefer doing that at all. Please only positive comments and suggestions that might ease me at least until i know it has a heartbeat at the end of the month.
