A vicious dead end

She was adopted
Never met her biological parents; they were dead; No siblings; No known relatives
Her adopted parents never hid this from her
She was raised like one of their own
Luck was on her side, and she found the ideal match
A very loving husband
A soul mate
Now she craved for a child
Somebody who has her genes
Somebody who can look like her
Another living person in this whole universe who shares a biological similarity
Luck was not on her side this time
She was sterile
A complete barren
