Sorry to hear of your 5hitty situation. It will undoubtedly improve with time, but yes, what to do until then is a challenge.
To an extent before i was diagnosed, but most definitely afterwards, i spent my time working on adapting or overcoming those newly found inabilities and hardships. Easier said than done i know. I also acknowledge that what ailed me is far less than what many / most are stricken with.
But being branded an MS’er allowed me to realise that improvement was always likely, but by the same token, a risk of accumulation was also a real threat. I decided early on “to hell with letting the symptoms simply wash over and take me!”
For a time, writing and typing required a modified technique and an adjustment of reasonable expectations; quite a challenge given that i remained at work, attempting to portray ‘business as usual’.
Walking and balance, not to mention occasional vision blurs also allowed me to practice a facade of normalcy. Essentially, although things felt like crap, i was determined to carry on as if nothing was going pear shaped. I didn’t want it and i wasn’t about to take.
For you (and everyone else) things are bound to be similar but very much different. But if i were you i would be pushing myself to do as much activity and even exercise i dared to think was possible; to push through it all.
And make cheese sandwiches, morning noon and night! This is just one of your life’s little challenges. Embrace it. And the very best of luck to you.
