Certainly there are a lot of factors to consider. Consider whether there is another job you could do elsewhere with less stress and a new pool of coworkers. For myself, when I recognized that the job itself was too stressful and too physical, I worked to find a less stressful position at a different agency (more of a desk job). I did that for a year, and then realized I needed even a slower pace. I tried that at another agency (also for about a year). Then realized when my physical self could not keep up with the daily activity, that it was time to stop. So for me, it was a progression of different jobs over the course of several years. THEN, I knew for sure that it was TIME. And I can see that was the right and necessary decision. Focus on what your body and mind can do. Don’t focus too much on the colleagues, because you can have that anywhere. At the same time, don’t feel GUILTY for needing to make a change…whether that is another job or something else.

I wouldn’t walk away , however , if , after reasonable adjustments have been made you really can't continue , let your employer terminate your contract . Your employer might be more helpful than you expect. Could you cope with a less demanding role and/or reduce your working hours ? Get Occupational Health involved. Are your colleagues aware you have MS ? If you don't feel your employers are trying to help you get in touch with MS Society they have employment law specialists who may be able to help you. Good luck and take care .
