You have to grieve and you have to re-frame your expectations - both for who you want them to be and for who you want you to be to them.
It's a tricky process - and it can take YEARS in therapy. You'll get there, if you work towards it.
I, personally, think cutting off contact is probably the easiest way to go. I also think it's very smart and intuitive that you want to create an environment for your daughters that is different than the one you had..... so many people just replicate..... so good for you!!!!!
I know one exercise a therapist had me complete once was to take a sheet of paper and write on the left hand side all of the things I thought an ideal family should do.
Then I crossed off all the things my family DIDN'T do. Then you re-write the things that your family DOES DO into the middle column. Now, here is where you get your control back. Are these things ENOUGH? It's not bargaining. It's black and white. Here is what they can do........
Is it enough for them to be able to do these things? If so, then you re-frame your expectations and you "agree" to yourself that you will only expect and judge them for what they CAN do. You grieve for the loss of the crossed off items.
If it's NOT ENOUGH, then you cut ties. Then you grieve for the loss of your family who can't be what you need, even with re-framed expectations.
I also think that you have to go back to your original list and look at the items that you cross off.... these are still valid needs and wants. Who will fulfill them? You seek out people who will fulfill these roles.
Good Luck.

ETA: Oh, I also think that it helped me to feel sorry for my mom instead of being angry at her. I could be angry at her because she wasn't a good mom. But when I had my daughter I actually felt sorry for her because she CLEARLY didn't get the joy that I got from interacting with my daughter. So, I saw that she had really missed out.... as a person, and a mom, and a wife, by being who she was. And I felt really sorry for her. It made it a bit easier for me to forgive her once I realized that.
