Fear and anxiety after a loss

I lost my baby August 28th it was a normal appointment no pain no bleeding no nothing. I was supposed to be 11 weeks, and the ultrasound showed baby stopped growing at 8.

Since getting this news I hate to be alone, Sunday nights are super hard I normally breakdown crying because I don’t want my husband to leave. ( he works nights so I don’t get to see him much during the week)

Does the fear and anxiety even go away? I feel so alone and I feel so many emotions I’ve never felt before.
