SkyWhite,
I have been challenged this way myself. What you need to realize is "creativity" is connected to our "emotionality" and when that is disturbed as you are sorting through that now, it interrupts with "feeling creative" because "feeling" is an emotional and is often expressed in our art, be it writing or painting or pottery work or whatever the creativeness is.
You can get that back when you settle all that emotional turmoil in your mind that is interrupting your balance in what we call PTSD.
