@laaa Yes emotions affect our symptoms. You don’t mention if you are on any Disease Modifying Drug.
If you are on one and are having a relapse perhaps you need to contact your MS tea,.
You mention that most people around you have no idea that you have MS. What a strain that puts on you. Does your work manager, occupational health know? Maybe they need to. At the moment sounds like you could do with being signed off sick for a while. Just a thought – with the benefit of hindsight ! ;-( Rest, rest and more rest is my prescription.
Hope you feel better soon.
