Absolutely. I've gone through periods where simply opening my laptop would almost invariably result in what I can only describe as a low-grade panic attack. If that's not PTSD, I don't know what is.

I've been taking a break for most of the last 6 months, and am only just starting to get back to 'normal'. I'm not at all convinced that I'll ever fully get back to where I was pre-burnout, but at least I can check my email again without provoking a fight or flight response.

If you have the financial resources to do so, I strongly recommend you take some time off - be away from all technology and spend time in nature if at all possible. Focus on sleeping well, eating well, and exercise.

Trying to power through what you're feeling might seem heroic, but you could end up doing lasting damage to yourself.
