I am terribly sorry to hear of the passing of your dear Mother...that is so sad, and I can understand how it would take it's toll on your creative writing, and focussing. Definitely focus on yourself, and take as much time as you need to heal.
To have lost such a cheerleader in your life, and a real Human Angel to others, I cannot fathom the shock and pain... :(
Sending hugs and love. Take as much time as you need. We will be here.
