Do tell your boss & team, but after you've thought a little bit about what you want your next steps to be. Their reactions can vary a lot - bad bosses might instantly fire you and look for someone else who's more productive, good bosses will work with you to improve your well-being while you remain on the payroll. You should be prepared for the former reaction even as you hope for the latter. The answer to the next question will depend upon how the conversation with your boss goes. You might want to completely disconnect and quit. You might want to work 1-2 days/week, supporting your team for questions but moving off of deadline-critical parts. You might want to shift into a different role entirely; oftentimes doing something different can cure burnout. Some or all of these options might be available to you depending on what your boss says, or he may suggest something entirely different. For the last two questions - I've heard that burnout is basically the result of loving something or someone for a prolonged period of time without them loving you back. Code will never love you back, which is one reason why tech and other knowledge workers are particularly at risk for burnout. But it happens with politicians, managers, and romantic relationships as well. It sounds like coding is a major part of your life; as hard as it may be, you may want to cultivate other things you love (perhaps including hobbies, or people) and view your work with more professional detachment. Yes, this probably means you'll be less effective at it, but it's also more sustainable.
