NOT a fun thing to have, I promise you. I utterly hate it. When I have writer's block, it takes a while to write something, and what I do write isn't up to par for me. I hate that feeling, because writing usually comes so naturally for me (almost as easy as breathing :3).
I'm glad I finally got over mine! It makes me feel so useless when I can't write >.<
But for now, I'm back on track. Thank God for small miracles!
