Ms Sorrell has recently tried going to Bude on a bus with a wheelchair loaned to her by the Parkinson's Society.
"It was a lot of hassle because you have to pre-warn the bus that you wish to travel and then you have to have someone with you as 'a pusher'," she said.
She said the closure could mean she will have to consider moving house or going into a nursing home in order to retain the small amount of dignity and independence she has.
Another angry villager, Ray Elliston, said: "We're not allowed to cull badgers, we're not allowed to hunt foxes but the government and post office policymakers expect the elderly and disabled to crawl six miles to a post office."
There will now be a period of consultation before the closure plans are finalised.
Members of the public can email their comments to consultation@postoffice.co.uk or Info@postwatch.co.uk
