AbilityNet is an organisation that provides IT support for people who are older or have disabilities who are struggling with their computers.
During 'normal' times one of their volunteers would visit your home to help. At the moment this is suspended but they can still support you remotely if you need a bit more help.
If you need a bit more help mastering Zoom, your emails or other IT questions they may be able to help. They are volunteers so they may be limited in what they are able to offer and will not be able to solve all problems.

Last year they put together an MS-specific guide to how they can help as well as a blog describing 13 ways a computer can help people with MS. Click on the lines below to find out more.
