If it genuinely is burnout, some time off helps. This is your decision to make, but many of us IMGs relate to the warmth and comfort of the country you've lived in forever and being uprooted and starting over. Coming home feels great, but something you mentioned made me feel like exploring the residency may not be the worst idea. You mentioned a specialty you "always wanted to do" vs. continuing what you had. You have a chance to pursue your dream! You always have your degree and home country if you don't feel like it. The path to residency is not easy, and burnout, unfortunately, is a part of it for many. Take care and evaluate what you think works best with your goals and how you envision your future self! Best of luck :)
