Yes, the emptiness is devastating.
Mouse, allow yourself the anger. Get a ziplock bag and fill it with ice cubes. Wrap it in a towel and smash the %#@&#! out of it.
In a way, I think it's ok that you are feeling this anger. I distance myself from my anger too much and then internalize it and take it out on myself. It feels somehow like a moment of growth, but I can't put my finger on it. It's as if something is brewing or stirring inside you?
You have such a solid relationship with T, I'm sure she can take it!
Take care.
