It takes time to recover from burnout - sometimes months. The best thing for you to do is just let that take its course, and not try to push yourself back to 100%. That will only bake in the burnout, and it'll take longer for your to recover. So go on holidays, meet with friends, read fiction, find some new hobbies. Whatever gives you pleasure, and isn't work, or an attempt to push yourself. And with time, you will find yourself returning to how you were.
