"Hard Times Come Again No More" can be a prayer that it never happen again. A little verse tinkering could make it apply nicely.

Instead of portraying the painful side of the isolation and persecution, why not inspire with the answer to it? "I Will Stand Fast" by Fred Small. Verse Two does not fit your occasion (it's actually an incest song), but the rest says you will not forget her/leave her alone in memory.... it says we stand fast (for her and with her) against isolation, persecution, etc.

I WILL STAND FAST
(Fred Small)

The echoes of childhood whisper violence
Cold wind beating out of the past
Rage in your throat, muffled silence
Hold on, I will stand fast.

In the darkness your guardians had left you
Cold wind beating out of the past
None to hear your cries, none to defend you
Hold on, I will stand fast.

I will stand fast, I will stand fast
You are safe in the daylight at last
Nightmare and fear, they have no power here
I will stand fast.

I will listen to the terrors that tried you
Cold wind beating out of the past
I will cradle the child that breathes inside you
Hold on, I will stand fast.

Though you take the shape of a hundred ancient horrors
Cold wind beating out of the past
Though you strike at me and flee into your sorrow
Hold on, I will stand fast.

I will stand fast, I will stand fast
You are safe in the daylight at last
Nightmare and fear, they have no power here
I will stand fast.
