Congrats on the Ah Ha moment London.
Not that anger is that fun to feel but I tend to think when your feelings change, it means you are cycling through some important stuff and making progress. Probably the sadness will come back. Maybe some numbness. More anger. Perhaps laughter. More livid hot anger. Welcome all of these. They are part of the journey.
Congrats again. You are not stuck in this. You are moving through.
And keep posting as NONE of this is easy!
