You might be misdiagnosing your children.
My siblings and I all have had some sort of issues due to our childhood home life. Our parent split up when I was 18, the siblings were younger. My mum and some of her family insist that our issues were caused by the divorce. This is nonsense.
The issues were caused by living our formative years in a shitty toxic atmosphere. The divorce meant that other people had to admit that the marriage was obviously shit. The divorce happened when the shit was at its worst. Our issues were not caused by the divorce. The divorce just shone a light on it all.
I'd bet it was your bad marriage that damaged your children. The divorce may have stopped them being able to pretend to outsiders that everything was normal, which would be difficult for a child.
When you talk to your DDs perhaps don't talk about the divorce as if it was an isolated random event like a life changing car accident. Talk about the troubled atmosphere in their childhoods instead.
