It may suck. It’s supposed to...
It’s hard to convince yourself that your novel is taking shape, word by word, no matter how horrible you’re convinced it is at the moment.
Think about what happens when someone builds a house. There are several homes going up in our little town. I stroll past the building sites on my daily walk. These sites are messy. They start off with a big hole in the ground, then stuff gets put into the hole. Eventually the framework goes up… weeks or months later, there’s a house, or several townhouses.
Yes, it sucks. It's supposed to. Creativity is chaos.
Keep writing anyway. It WILL all come together, just keep writing.
