I know how you feel, that I do. It's so hard to go NC, and so hard to deal with the pain, but it's the only thing you can do.
It's been 7 months NC for me, and every day has been a struggle for me. But, it keeps getting a little teeny tiny bit easier, and eventually, I trust I will heal and be over the N completely. Not easy, but what is the alternative, right?
Good for you for finding the strength to go NC and cut the N out of your life. Keep praying and focus on making your life the way you want it to be. When you feel you hate your life, make plans to do small things to change it. I've taken lots of little steps in the last 7 months, and guess what?? They really add up, and my life is a lot different now than it was then. And I don't hate it anymore. But it took time and actually making changes. Keep NC!!!!
I wish you well.
