I just want to say that i've had several burnouts throughout life so far, the majority being during key projects for my school/university. This has become a recurrent event as it is now happening also during my work. Anxiety feeds it. In any case, i also have history of grand mal seizures and sleep deprivation is one of the key triggers for this. I'm actively trying to improve my lifestyle and take control of my life. As my neurologist said: focus on psychohygiene.
