What does it take for you to get yourself to a place where you are feeling confident enough to withstand W's possible storms? Where you are solid and comfortable enough in your path that her reactions are just minor weather?
When have you had a taste of that feeling recently? What can you do to make sure you get a taste of it every single day? What are you doing each day to practice stepping out of your comfort zone?
Perhaps one helpful tool... When describing or thinking about your situation, turn it around from thinking that something is being done to you. Describe everything as "I am choosing..." Every day, say out loud what you are choosing. Before you step down the stairs, "I am choosing to [go down and isolate myself/step out of my comfort zone and engage with my family in a different way]"
