I'm paddling in this boat too. I had an agent for my first YA novel and she submitted it to about 7 places in the six month's time we worked together. I had submitted it before I connected with her and wound up getting an offer from a publisher that way, while her submissions all declined, but one, but passed because they couldn't offer an advance. Why she sent it to them was beyond me, she should have known they don't offer advances. Well it wound up my agent dropping me like a hot rock when the one offer was too low for her to work with. I did the same and declined it too. Even though there was that small itty bitty advance, the contract was poor. I had asked my former agent if I could go back to one of the editors that liked it, but didn't offer the advance...thinking maybe they have a better contract. I did and they were still interested, but through the whole process I had made revisions, so I sent them the newest copy. I still have yet to hear back. This particular ms. is out with only a selected few editors...since it was subbed before, during and after my agent experience.
And of course, while I waited through this whole process I wrote another YA novel and is out on submission to new agents. I have some better interest in that then I did in the first one. As someone said before in this thread, there was interest...but the story was under developed still. I knew in my heart, being that that one was only at 35K words, it would be a hard sell no matter what how many liked it.
From my experience, my stories are pretty good, and commercial-like, but way too short. Over and over again, I got comments from editors, "not literary enough" "needs more character development"...so this time after the fourth book, I finally listened and my newest one of sub is at 52K with a high concept. But I've already had declines on one full and two partials. Seems like my query is great, but once they start reading it, everything changes.
So I came close many times. I keep working my way up with publishing credits and writing my brains out. But haven't made it where I can pay all the bills yet. May never get to that point. I just don't have the heart to stop my dream coming true. It's been 8 years of writing, 3 years with novel writing and it's effin hard. But I keep writing and keep trying, why? (I used to ask myself that every day) I just now came to the realization, I will write till I die. Even if that means to stop trying to sell it and concentrate on just writing along for a while.
Some of us writers forget why we write if our work doesn't sell. I too, seem to lose interest if I have to take time away to have to research an agent or a publisher, or market or whatever the case. Everything that takes you away from the writing itself is what sucks.
Anyways, that's my standpoint. What's that old saying "If at first you don't succeed, try, try again..." (totally cliche, but it seems to work...eventually, right?) LOL
