This is it, as bad as this experience is there is the silver lining with the outpouring of love and support from everyone around you.

Who knows the why of anything like this.

The worst thing for your sister will possibly be the uncomfortable reaction that friends will have around her, when they talk about babies and births.

Your sister will get better but it will be slow and incremental, and if she can talk about it, and cry and acknowledge the pain even years from now, with a loving friend ... all the better.

How is her husband coping? He needs help too.

Best of luck in helping her heal and keep your eyes and ears open to the great many ways those from the angelic realms can provide welcome assistance.
