Wanted to reply, but kept forgetting as I'm perpetually busy these days...

Don't beat yourself up too much over it, it happens. Hell, it sounds almost comedically similar to my own situation. I thought I'd have loads of time to write Agate's Vigil when I quit my business as well, and yet, so much time was spent just pacing around in circles and not writing. If the motivation is not there, it's just not happening.
At the same time, though, there were a few instances where I just had to force myself to sit down and go "okay, not feeling super into it, but I said I'd do this thing, so I'm going to bloody do it". It's a balancing act. Creating stuff is fun, but there will be moments when it's no but if you want to finish it, then you have to work through those moments, too.
As for your other projects - do them. Come back when the motivation is there. That's what I did while writing Agate, I'd get flashes of inspiration and go off writing COMPLETELY different short stories, then come back to it when the motivation was there again.
