Welcome! I'm also a 42-year-old single woman with no kids, looking to retire next year. Your finances look very good. My expenses are a bit lower than yours, but I live in a lower-cost area and have my house paid off. I'm also planning to travel a lot after I retire.
I would hold off on any condo purchase until you've spent some time living overseas. You may find you never want to come back. Sounds like that's what you're planning to do in any case.
I feel some anxiety about retiring too even though I've analyzed all the finances to death and they look good. I'm guessing the anxiety will get more intense as the date approaches. My parents retired with a very solid financial outlook and my dad had stress-induced hives for a year after giving up his income, believe it or not. So I guess all I can do is prepare mentally for some anxiety to inoculate myself against One More Year syndrome.
So good to see your post Inky! And thank you for your kind words. I totally agree - retire early is a life changing event, one that can bring more stress than working especially during the early years into RE. We will have to rethink about who we are, what we want to do, and search for our purposes in life. All the stuff that we did when we were teenagers! It is more than finances that we will have to figure out.
I plan to spend a lot of time, quality time that is, with my elderly parents in Asia, reconnect with my friends, travel, and visit friends (I am fortunate enough to have friends living all over the world that I can stay with)... I will likely fill the first 2-3 years of my retirement with traveling and financial planning. I will try to keep myself busy, so I won't feel lost or depressed.
Good luck with your One More Year Syndrome! I am dealing with mine and it is getting lousy - no, my work ethic is getting lousy.
