I'm so sorry you're going through this. It is awful, truly awful. I spent a lot of time speaking to the wonderful ladies at ARC and one of them told me it was awful, one of the worst things most people ever go through in their life. The point is, they do get through it. This made me feel oddly validated and reassured.
I am now almost 2 months out from mine, not okay by any stretch of the imagination but better than I was. Talking has helped, both to friends and to a good therapist. Long walks and nourishing food have also helped as have absorbing films and good books. I am also trying to take joy in small things, I saw some daffodils today,signalling Spring which made me smile.
In all honesty I wish I had a time machine, and you could jump in it with me to a place where everything doesn't feel so heavy and sad, but we just have to go through it. Sending you a big hug, this too, in time, shall pass.
