Confronting past demons (or teachers)

This past month I took part in an online workshop. One of the aspects of that workshop is drawing.
When the drawing week began I happily started and then I just couldn’t draw anything. I just sat there, dumbfounded, and wondered what the heck happened.
Being well-versed at conversing with my fears, I soon had the answer: because of the one horrible, scary and awful art teacher I have had in the past.
This is the thing with sudden onset of fears or blocks, they are always rooted in the past. There is always a reason from your past for freezing on the spot right now.
What does your fear drag you back to?
