Yeah, Diff...you are getting slammed from all different directions. Hang in there.
When Ms. Wonka first left, I couldn't function for the first two weeks. I had a friend come over and stay with me. Bless this friend's heart, she made a to-do list for me. That helped me IMMENSELY. It gave me a focus and allowed me to check off each item when I've completed them.
Such dark days...phew.
Nowadays I do my own to-do lists that helps me breakdown actionable goals when it comes to work. Even if you do ONE single thing in one day...that's accomplishment by itself. Even if it is 15 or 30 minutes.
