Jodie this is grief, and it is natural and no one can tell you how long it will last. Please don't judge it, or yourself, as something negative or a failure. You have been through a traumatic relationship and a traumatic breakup and it's only been a week. We don't move past things that fast, we just don't. Have faith that you are doing all you can do with therapy, meetings, rest, and no contact. Be nice to you.
