Again, you need to apply through the local council and there's a form for your doctor to sign. There are strict rules about who does and doesn't get the permits, but I know many PWCs who have them. These will allow you to park in disabled parking spots and to park for longer in a regular parking spot. And of course you can do lots of things on the phone. Most bills have a number on the back that lets you pay by credit card if you call up their number.
Most banks offer phone banking.
And shops are often happy to send out catalogues for free if you explain you're disabled and find it hard to get to the shop yourself. It's always worth trying as the worst that can happen is they say 'no'. As people with CFS, we're often used to ridicule and people trivialising our conditions. This can make us forget that most people out there are understanding and helpful. So give people a chance to be helpful by politely asking for what you need.
