I don't know about anyone else, but it can be a bit of struggle at time to work while experiencing low mood, motivation problems etc. Add physical conditions to this equation and it's even harder.
At the same time though, work is good, it takes your mind off things, it keeps you motivated, it helps to be around other people, having a natter etc.
I also stagger my Annual Leave so that I'm never working for too long between times off.
Flexible working patterns are also very important and good support in work.
