long hair and can no longer reach to comb it or put it up?
get a short hair cut - i did and am delighted. it looks great, it's taken ten years off my face and i don't have to feel frustrated about not reaching the back of my head!
can't wrap the bath sheet around you?
lie the bath sheet out flat on your bed and lie yourself onto it on your back. then you only have the front bits to wrap across you.
difficulty getting tops on and off?
choose looser tops with wide necks. golden rule for poorly arm is first in and last out.
i learned both of those the hard way, struggling to get a tight jumper off on my own. i felt like i'd wrenched my arm out of my socket.
driving becoming uncomfortable (if you haven't already had to stop)?
pull the seat further forward than usual so you don't have so far to reach.
work involves using PCs?
if you can, get someone to check over your workstation to ensure you have the physical supports you need - maybe a trackball mouse, wrist support etc (this facility is available if you work for a local authority and they will buy the equipment, ask anyhow)
i'm 3 months into my second FS ,so i've got to know the ropes a bit now. it does end - there is light at the end of the tunnel.
