I agree with you wholeheartedly, especially about the worrying. As someone who is prone to worrying anyway, toss in even a mild case of writer's block and I'm a mess! lol It truly can be a difficult cycle to break. For me, it sometimes helps to talk it out with a friend. Not only do I gain a different perspective but quite often, new ideas come tumbling forth. More often than not, it can start the ball rolling slowly forward.
And welcome to ChaosKitten, Darth Xelleon, tinyteeth and ChibiShiva. I hope that you all find many new and wonderful things here at AFF and may the curse of writer's block never shadow your doorstep.
