Keep doing what you're doing now: taking a break. You evidenced some initial interest in drawing or modelling, perhaps go back to doing that for a hobby. Reconnect with your friends, as you are. Perhaps go on a trip. You're burned out because you've been pushing yourself too hard.

Give your mind some time to relax. Take all the time that you need. Maybe a few months. Maybe a year or more. The time will come when you know you're ready to get back to changing the world.
