Not a constructive comment as such (ok, maybe a little), but I am in a similar situation. I'm working on polishing a novel at the moment and wondering what I want to do with it next. I've worked too hard to just let it rot slowly on my laptop, but I don't fancy writing to publishers etc etc. I suppose if I want to publish a novel I have to do that, but I don't fancy it.

Has anyone else read your novel? I would suggest asking a friend (someone you trust to be honest, brutally so if they have to be) to read it and to tell you what they think. You may be happy with it, but your friend might see something you don't, a plot hole you think you've mended, but haven't, or a character motive you haven't been as clear as you think you have. Is there a writing group or book reading group near to you? It may be scary, but it might be worth considering asking a book group to read your novel for you and see what they think. If not there are plenty of critique circles online.
