At 22, heartbroken, depressed, and unsure about my future, I craved novelty and adventure, so I packed up my life in England and moved to Japan. Now, 31, living in Tokyo, and more secure than I've ever felt in my adult life, I can't help but feel that creeping depression, pushing me to pack my bags once more. In my early 20s, upending my life felt exciting. Now, in my 30s, it just feels indecisive.
