Mrs George sorry to hear MS has flared up on you.
Don't feel that because you've had a few relapses in a short space of time that it will be just getting worse from now on - not necessarily so. I was having 4 relapses a year a few years ago. Now I have about 1 a year and very mild at that. Long may that continue (she says frantically - Aug/Sept has always been my high-risk time of year! )
The thing is that it's a warning from your body to start consistently taking it easier from now on. I felt, for me, it was like a bereavement. I wanted to keep going out each weekend dancing, drinking, smoking, out til 4am, working full-time, doing classes in the evenings, swimming, cycling, tai-chi, etc etc. It took me so long to accept that I wasn't normal any more, and that I would end up in bits if I didn't cut down what I was doing.
Sometimes even now I feel jealous of my parents for example or older people in work - people who are 30 or 40 years older than me have better energy and stamina, but thems the breaks with MS.
PLEASE be good to yourself now and hire that cleaner, cut out the volunteer work, and take the time you need to get over this relapse.
