I feel your pain! I was a criminal barrister on the Northern and N.E. Circuits. I was diagnosed in 2017, after two bad relapses which put me in hospital. I emerged with my ability to walk badly affected. The travel had been bad, as had coping with badly designed court buildings, which are not remotely disabled-friendly. I noticed that my memory was getting unreliable, and I had speech difficulties. All in all, far from ideal as a barrister…
I just couldn’t go on, and retired in ’17. My stress levels have gone down considerably, which can only be a good thing as far as my M.S. is concerned.
Good luck with whatever you decide to do.
