Congratulation s, both of you!!
I always feel the same way. Finishing a story gives me a tremendous feeling of accomplishment, especially when it's a story I've been working on a long time, but that makes it even more bittersweet. Once you're done relishing in the reviews you get for the end of the story, you're like, "Okay... now what?" It can be hard to go back to another story or start something new. But still, finishing something is awesome!!!
