Hi Tuppence
This does happen quite often, you cannot appeal via your journal, but you can request a Mandatory Reconsideration. If you cannot share a bed due to a condition then you will need to get a supporting letter from your doctor or other health professional, then up load the support letter on to your journal.
One of the advantages of using your journal is that it is date and time stamped whenever you make a comment or the DWP asks you to do something on the To Do tab.
