“What was here is no longer; there’s now something else” 

You are riding into the sunset with this situation. Nothing grows without death and from the ashes something else is born and this requires you to stand up & be present. Let them know you are a force to be reckoned with. Set firm boundaries, stand your ground, be clear & don’t apologize for asking for what you want. You’ll not get anything unless you ask for it in no uncertain terms. Express your truth from a place of power. Adopt the traits of a true warrior - one who operates from a place of strength, truth & dignity. Work from a place of logic and heart- not wayward or erratic emotions- but a masterful place. Use your head moving forward-you’ll need it for building this new reality. Actions based on self-control wisdom & strength will have you masterfully creating a reality better than the one gone by.
