Hi, Toast.
I feel your pain, I really do. I don't know how much I can help you, except to say that I've been there, done that, got the T-shirt.
I've dipped my toe in various writerly pools including screenwriting, part of a novel, short stories and poetry. Convinced myself I was sprinter not a marathon runner and that the short story was my natural home. I then - can't quite remember what happened - but I then convinced myself I was actually a poet. Have since re-discovered that my great love is the short story and that is where I am now concentrating my energy.
All of which is of not much use to you except to illustrate that it can, I think, take a lot of running up and down the writerly scale before you really do discover your home.
You have decided that you are a novelist, which is great. But I beseech you to JUST WRITE and you will learn from every sentence you commit to paper (or computer screen). Jot down notes as you perambulate through life, write shorts, write poems, do 'morning pages' if they suit you (I don't, those who do will expand upon this if you haven't heard of it). By all means, start another novel. You have clearly learned, through the novel you have already attempted, so so much about yourself as a writer and how you should (and shouldn't write a novel). Trust that you have already learned much that is greatly useful to you. The more you write, the more the threads of writing will unravel and make themselves clear to you. Write, and may the force be with you.
I like you, Toast. And not only because I think of the song whenever I see your name. You have a great attitude and I get the feeling you can write and will find your way.
I haven't posted here for ages, but I really felt moved to respond to your thread. And not just because it's sunny and Sainsburys had a good offer on bottled beer this arvo.
There are at least two people here who think I'm the late unlamented Greentown. I'm not, but there's every chance that saying so will convince people that I really am! Ah well.
All the best, Toast. You are definitely going in the right direction. Write and all will be revealed - writing is a mysterious business and the fog only clears when you do it, do it, do it.

<Added>Oh, and read, read, read. If you lack the time to read whole novels, read the openings of novels on Amazon. Very useful exercise.
