@Christian Bundy missed you here!
I've burned out on SSB as well, in my case deciding to be more of a user than developer helped a lot. I've been using this more since I don't really need to work on the code part of it.
I'm quite relieved to learn that the burnout is focused on SSB only, I was a bit afraid here. Happy to have you around, and excited about the future retrospective post.
A suggestion of structure is:
- What you aimed to do.
- What you got right.
- What was fun.
- What you got wrong.
- What was terrible.
- Given what you know now, what would change.
- Cautionary tales, advise for other developers.
- What would you like to do next (which doesnt' mean coding)
