I was in that same spot. I really had a struggle initially with spending time with my D. I was just down and distraught and the idea of spending "quality" time with her upset me, as strange as that sounds. I guess, because every minute I was spending with her made me think about the past family situation that we had. There is no denying that life is changed, at least for now. You have to FORCE yourself to "mom up" for your kids. Just like GAL, after you get back into the swing it gets way easier, at least that was my experience
I started AD's and pretty quickly saw an improvement in my ability to control my emotions. It definitely took some of the peaks and valleys out...not all....but definitely improved. If that is something you are open to, no better time than the present.
