Thank you for replying, it would be great to have an end date, wouldn't it?

Right now I feel like I'm counting down days to when my sick pay ends, I've got rather fixated on the idea that when that happens I will somehow be forced into a recovery. If I'm still not better by then I'll have to make the decision as to whether to return to work whatever state I'm in or try to get my employer to medically retire me. I'm not yet 50 and while the prospect of working until I'm nearly 70 holds no attraction, I don't want to be "retired" either. Knowing that my depression would last more than a few more months would make that choice a bit clearer.
