Oh Sweetteewalls, I am right there with you, I feel the same pain. It feels like your heart has been torn to shreds, doesn't it? I removed an item that belongs to AXBF from my home yesterday and just broke down sobbing and crying. Whereas normally I get rid of someone's stuff very quickly and all at once, I am being gentle with myself and taking it slow, as I have suffered much loss and have become depressed from it. I am regaining control of my home, slowly but surely.
Here is what has been helping me:
There is a behavioral "formula" for vitality, joy, and empowerment. That formula is to invest your time, attention, and emotional energy where you have power: your power to act.
Not sure where I picked up those words, maybe in a George Simon article. I just read it as often as possible to remind myself that the way out of this pain is to continue to actively Pursue things that are in my own best interest.
