Is it down to the lake I fear?
Hi Andy, this resonates with me as I've been through several style changes over the years. Sometimes you just feel like you want to give it all up after you have exhausted your ideas with a particular 'project', or phase. I guess that's why most bands split up after a few years - they end up writing the same songs over and over, and then just get bored, as the magic has left.
I reckon, though, if you just take a good break - for a few months or years even - there's every chance you will come back again refreshed and raring to go as a music maker. Maybe you will have a go at a different style. Look at Bowie's career, for instance, he kept reinventing himself of course across his entire songwriting lifespan- and always sounded fresh and interesting in my view.
My hunch is that music making is in your blood and we'll see you back again one day with something new, and something that challenges you again to create something different. But your last project has been great, very inventive. So I for one am looking forward to your' 'last song'. Good luck with that...and with whatever lies ahead.
