This is the tough time, TG. Not that the rest wasn't, but once I made the huge decision to leave the relationship, and the dust settled, a bit of the anxiety set in. Even though I'm still in my home, all the old routines changed, AH was not here to talk to, etc. I have my cats, like you have your dogs, and all these months later my life is very, very good.
In the last 10 months I've made some good new friends, and I know at least a couple of them will be lifelong. It's all a process and at first seemed to drag. Each day is a little better and I hope it's that way for you, too. I think it will make a big difference once you are in your new place and start making it your own.
Thinking of you.
