I have been working full time with PTSD, BPD and Bipolar II. I have never taken a vacation, ever.
I have no choice but to work full time. There has not been any other option for me.
It has been very difficult and at times my performance suffered but as I said, going into disability or taking time off have not been among the options that I could consider.
I am sure you can do it.
What do I do when I am triggered at work? Happens more than I would like to.... I go to the bathroom and write about any emotions and then throw away the paper. Then I do some breathing exercises. If I have time and if the weather is good, I take a three to five minute walk and then get back to my desk.
