I don't know anything about cymbalta but wonder if there isn't possibly something else to help you through this. You may ask your T when you talk to her.
Maybe abilify just wasn't the right med.

Could it be that you have been working at too fast a pace in T? Sometimes we are not ready to handle something and when we push too hard we are not ready to cope. I am having very frequent flashbacks and nightmares and we have backed off some of the trauma therapy and are concentrating on some coping skills so I will have something to fall back on as it gets tough again in therapy. Unfortunately it has not reduced them but hopefully now that I am starting back into the trauma therapy that it will help.

I am so sorry that you are having such a hard time right now.
