In a similar situation, I decided to take a leave of absence with no plan for what I was going to do. Since I wasn't sure I'd go back, I made sure other people on the team were prepared.
Then serious family stuff happened and I was happy to have the time to deal with it. After the leave of absence was up, I still wasn't sure and asked about extending, but they didn't go for that so I left the company.
Since then I've learned to play the accordion and now I'm tinkering with electronics to come up with a new musical instrument. No real desire to get a job. After a while I decided I'm fine with simply being retired.

So I'd say try the leave of absence?
