Artist's block

For about three years now, I have had the worst case of artist's block. I have not been able to draw so much as a straight line. I used to have little lulls in my drawing, but never for three years. I took to writing as a way to get out some of my creativity, but I miss getting an idea, picking up a pencil & seeing my imagination come to fruition right there on the paper. I've tried even just doodling & I can't get anything out.

Any ideas on how to shake it?

Anyone? Anyone? Bueller?
