Not that this is easy but... When your faith is up your fear is down. When your fear is up your not putting your faith in the Lord. I am an awful worry wart so I go through this struggle all the time. I am fighting it now with our 12 week old puppy!
Chewy got fixed last year and I was a mess... But it went well and the vet office called as soon as he was doen to let me know he was ok. I went shopping for chewy while he was in surgery... it helped to keep my mind off of stuff. It was hard but I had to wait all day to pick him up!!! I put his bed in between my husband and me and Chewy slept with us for 2 nights until I felt his was ok. He sleeps with us all the time now!
I will be praying for your baby and you. Keep the faith!!!
