It's a hard thing. I still can't look at the letter that I received from Kensington. But I soldiered on and submitted to Ellora's Cave and LooseID. I won't hear about those for a few months but until then, I've decided to take the constructive criticism to heart. I've decided to revise my story, to add a bit more conflict, which is what the editor's complaint was with my story. I'm submitted the story to my critique group with the rewrites so I can see if I'm going in the right direction.
Rejections are a part of the business. I know that. I know that I have to grow a thick skin. That and write, of course. I've never been good at rejections. I have this whole perfection complex so if I'm not good at something or I don't think that I'll be good at something, I won't try it. But I know that I'm a good writer so the rejection hurts. I wish that editors had the time to expand on what could be improved in your writing. I know they don't but it would be nice.
I have to take this rejection (and the ones that will inevitably follow) and improve. That's all. And all is a lot.
