Caulk if you're the poster I'm thinking of, I'm so so so glad you're NC. From memory, you have had an absolutely horrific time of it 
That said, NC is never going to be easy, especially if it's NC with parents.
It is so like bereavement but not. I know that you can pick up a phone, but what you really want and need is never going to be at the other end of that phone. It's a process of accepting that the relationship you want isn't going to exist. So added to bereavement is frustration and anger that what you want and need isn't going to happen.
Fwiw I'm a few years in of very very LC (went from seeing aunt and wanker husband 1/2 times a week to less than yearly). It's now 4, possibly 5 years? I forget because it's not important.
You're likely to go from thinking about it all the time, then you'll realise one day that you haven't thought of them. Then the next time it will be a bit longer between realising, then longer still.
It takes time. But you need to be kind to yourself and allow yourself that time. There isn't a quick fix - I wish I could give you one though
