What can I do to recover from a short term burnout?
For a true burnout you will need to stop working, rest, and seek counseling/medical help. You need to lower your expectations of yourself and virtually eliminate what others expect from you. Ultimately, because work is about expectations (either self-imposed or set by others), I doubt that you can continue working and recover from a burnout. 

Given that you state that the burnout occurred over a short period, rather than a sustained year-upon-year effort, my advice is to take a vacation. Three weeks should do the trick.

Just remember, life is about enjoying it, not earning money, because in the end you will take nothing with you.
