Thousand,
Maybe start with a smaller blank canvas, take some pressure off and
let yourself relax with the artistic spirit you are feeling the need
to express again.
The blank canvas/page/paper can be intimidating visually, so scale it
down so you can have fun with it
I believe artistic expression is very close to one's spiritual nature and
the feeling of needing to be creatively expressive is a true gift.
So happy for you!
