Artist Block

For the longest time, I had artist block. It's much like writers block, where you feel like you're in a slump and lack creativity or inspiration, which is exactly what I had. Now mine isn't so bad, because I am working off pictures to create my portraits, but I believe I still qualify for artist block.
Every time I pick up my pencil, I can't seem to co-ordinate my hand with my eye, to create the image I'd like to have. I pick up my eraser, erase my mistake and try again. The same result. Than I erase and re-draw so many times, that my paper becomes a huge muddy mess of faint lines of past mistakes, that I need to start fresh on a blank piece of paper.
It's very frustrating, because I want to draw, but it's just not showing through in my work. So I decided to take a break for a while. Abandon my work completely until the time is right, and finally, it came back to me.
I spent hours drawing and drawing. Once confident enough with my portraits, I made it permanent with my micron pen.
I feel relieved finally getting back my creative side, that I missed for too long. I'm going to take advantage of this, and create as much as I can, before another artist block, and before I get too busy with school as I am near the end of the semester. What a relief.
