You don't really need to say anything more than you have in your post.
Have you considered asking for a home assessment, you will need the support of your GP to write to the Assessment Provider why you cannot attend at their offices.
You may be able to get a Paper Based Review if your GP is prepared to provide any additional information that the AP may require to allow them to do one.
