I think you're processing. You've been (quietly?) (slowly?) processing everything for the past few weeks. I think this lack of productivity is just you processing.
Slow down, Lynette reminded me yesterday. It's o.k. A lot has changed. Everything has changed. You're just processing.
This has challenged your identity - everything you've ever thought about yourself. And you, especially, are someone who takes awhile to process. It's normal.
