Should I be using a wheelchair or not?

I have what my neurologist calls, an 'undiagnosed neurological condition'. It affects me in lots of ways. 

Balance: I lose my balance easily and tend to fall over a lot
Memory: I forget silly things like my name, or date of birth
Concentration: Keeping focused on something like a TV programme
Migraines: Present as though I'm having a stroke, and my right side goes
Confusion: I get easily confused
Auditory: My brain tends to shut down when I'm in a noisy or busy environment

Because of these problems, my occupational therapist advised me to use a walking stick and a wheelchair, as I'd passed out in supermarkets quite a few times because of the noise, and that after walking a short way, my balance gets worse and worse and fall over. 

I always feel feel very self conscious in my wheelchair though, and once, a GP asked me what the hell was I doing with a walking stick? My psychiatrist, on first visiting him, asked what on earth was I doing in a wheelchair. But my psychologist said it was ok to use the wheelchair, because it enabled me to do more things. My neurologist didn't make any comment on either thing, and just said I was very wobbly on my feet. My CPN said it was far better to use the wheelchair and walking stick than end up in hospital with concussion. 

So so now I don't know where I stand? Pardon the pun. Am I ok using the wheelchair and walking stick? Or do I not use the wheelchair and walking stick?
