When is it time to use a wheelchair?

I think i would be much better off using a motorised wheelchair.

I dont even feel safe walking round my own home.

I have had quite a number of falls, some of them have really hurt.

I havent needed hospital treatment for any of my falls but theyve scared me enough to want to be in a wheelchair!

Can anyone advise me on how i make the transition. It would mean so many changes in my lifestyle i dont know where to begin?

I'm still driving and value my independance hugely.
