It's not exactly a full blown writers block. You can still write, just not as fast or as long and it gets hard to do. You get frustrated with yourself for not writing but when you do it, nothing seems to pleases you. You start over and over and over again and just can't get it to your liking.

Word of advise.

Leave it be. Its not going anywhere and if you keep this up, its eventually going to become a full blown writers block.
