Mary,
I have 3 friends who have had relatives in prison.
In two cases a husband and in the 3rd case a mother.
It is not as unusual as you may think!
You need to ask yourself a few questions as to why this is causing so much angst.
Is it the nature of the crime?
Did you give evidence to support a conviction?
Is it a wrongful conviction?
Or just shame by association?
Find a trusted friend and talk, talking will normalise the situation and hopefully help you come to terms with the sadness.
