Way to go! I encourage you to go for the Masters. In hindsight, I wish I would have "just because," but in my case wouldn't have made too much of a career-success difference in "those days" at least early on. I'm 57 and had a very good career on my BS degree. But you could do that somewhat easier back then, and my field was a decent specialty without a lot of others nippin' at my heels (for that critical 5 year starter/establishment period anyway).
Definitely take a little time to recharge, but +1 the suggestion to not wait too long. It can be hard to get back the right energy to jump back in.
You don't say whether your new degree(s) is career-driven, but if so, the Masters is almost a must these days for a leg-up in a lot of fields. My 28 yr old niece has worked two years past her Masters only to find she is now itching to move it on to the PhD. Very bright and hard-working gal, but not only is it a struggle for her out there like lots of folks out there now, but she is a bad personality and skills fit with the hard-driven field she chose, and would ultimately just as soon "impart" knowledge to up'n'comers on her own terms... versus duke it out in the cold cruel corporate world she unwittingly (rose colored glasses etc) thrust herself into.
Good luck on whatever you do. At 47, you've earned doing nothing in my book! A little bit of mixed messaage there I admit
