I'm traumatized from childhood abuse (but not sexual abuse), and knowing how many people are neglected/abused by their caregivers lets me know that:
a.) There is nothing about me that caused the situation. Since I'm a very strange human, that's good to know: They weren't abusing me because I was too hard to parent or because I didn't act like a normal child.
b.) "This too shall pass." Trauma has impacts on my life, but, with the example of others, I can move on and make decisions that help address the damage.
But maybe I've always misinterpreted the English phrase. Is there a different English saying that's closer to the Dutch meaning?
The phrase "misery loves company" makes me think of this Calvin and Hobbes strip, so I guess it has cynical connotations for me:

Though I wouldn't apply this phrase to the situation of victims feeling comforted by the knowledge that they're not the only ones.
It helps to know that you are not the only one who has suffered injustice.
"Misery loves company" is indeed a common attitude, but I'm not sure it's especially healthy.
