Exactly! I had a very severe case of a burn out. I LITERALLY couldn't move nor get out of bed for at least half a year. Getting to the kitchen and making food was like running a marathon. Lots of people around me didn't understand and wished me a good time off and "relax at home", when I was really sick and working so hard to get better. If you are seriously burned out a trip to London is the last thing you want and can actually do! She's clearly very capable of doing stuff, she's just tired of her routine, that's something completely different than being burned out. You are absolutely right re: depression, too. It's so overused by influencers now that people with real MH issues are not taken seriously anymore*
*Not talking about the ones who are actually suffering of course x
