I have similar issues. I am getting stuff done, but outside of simple one shot apps, it would have been quicker if I'd have written it myself.
Part of the issue is I like to build in a very specific way. Not just the architecture, but the particulars inside of the scaffolding. I like beautiful, elegant, well designed code. And that is decisively NOT what AI writes.
I'm learning to let go of being a coder, and take on something of a manager's role. I write a detailed spec, enforce design decisions with code, and ensure I've got decent test coverage. And then I put on my editor's hat, iterate, curate, and refine.
