I agree with lots of points Peter made (although I wouldn't put it as harshly and send you to psychiatrist - psychologist, at best, but you don't need medications for this - but that's Peter for you).
So yes, I'd say you're frozen by the fear of failure. It's so easy to fall into that trap. Please take it easy and, if needed, do some introspection and remember when art used to be fun and WHY it was so fun. Compare to how you feel right now and I'm sure you'll figure out a way. Maybe not at that instant, but it will happen.
, you are on to something
