After moving away from my family I got a lot better and started working full-time, but I took at least 2 sick days every month. And I worked with the most painful headaches just to keep the sick days to a minimum. After doing some exposure scripts and taking two weeks disability, I went back to work and did much better, but I still need at least one sick day a month and when triggers come I stay at work through some incredible exhaustion. I'm not sure if full-time work is the best for me.
I don't know anybody else with PTSD and of the people I've told, about 5% have responded appropriately. Most people think I should buck up and either work harder or exercise more. So, it has been really good to read so many responses to this question and see the variety of answers.
