Tell your team about the situation and that you need to disconnect immediately to help with your mental health. They will need to understand. You'll feel guilty but treat it as an emergency. I would take a vacation of 2-3 weeks, now. Get away and make sure you don't deal with anything work related, no coding, no email and even contact with the team. This applies to any personal projects. Basically, take a vacation to a Club Med type of resort with your suitcases and that's it. No electronics. Don't let your work know your contact info. Keep in mind that nothing bad will happen just because you decided to take a vacation. Once you come back, reduce your hours to just working hours. Close your mind to anything coding after the day is over. This is a must. Otherwise you'll fall into the same situation. If your work won't support you then you'll have to start looking for a new job. For the time after work look for a hobby that you can do where you can have fun and disconnect. Your goal is to use the hobby as away for your mind to disconnect from work. Do not obsess over it since then you'll fall into the same mindset that will lead to burn out. All this will only help the situation but only time will heal you but you need to reduce your obsession over work. Otherwise you'll be in the situation again, relatively soon. You can continue without doing anything and in 2 years from now you'll be in the same situation. The best thing you can do now is start the process of healing.
