As long as there isn't something seriously wrong (such as depression that leads to inability to enjoy pursuits), maybe that is OK. It could be important to be able to accept that you don't always have to accomplish something, and that your life doesn't have to be about maximizing how much you can accomplish. (Which is a different thing than saying it's OK to never accomplish anything or OK to consistently accomplish very little.) You don't recover from burnout or whatever else by driving yourself crazy with worry and guilt over how you aren't living up to some standard.

About the weird reactions, I've been through that after making a similar choice, and I've found that with some people, they are just not even slightly open-minded about it and they are going to judge you instantly. You can't do much about those people.

But with other people, their reaction will depend on how you present it to them. You've just told them you're doing something far outside the social norm, and they're going to be thrown for a loop and wondering why and how to understand it. They don't know if you're a lazy, broke, aimless loser or a person who has a plan and is doing this for some kind of purpose and real benefit to making their life better overall. You're going to get a whole different reaction depending on whether you say "Uhh... so yeah, I'm not working anywhere right now" or "I was fortunate enough to be in a good place financially, and I really wanted to take a year off, so I am". The second one signals that you're in charge, you're content with what you're doing, and your successful enough to give yourself the opportunity.
