When SS tried to discharge my mom home I just kept repeating that she lived alone, was a vulnerable adult and they were putting her at serious risk. Eventually they agreed for a six week assessment bed then decided that she had capacity and could return home with carers three times a day. After about a month she refused the carers and it was left to me - we muddled along for nearly four months until she started to wander at night. After being returned by the police I was told she could not be alone then the battle to get help started - help was promised 'tomorrow' but tomorrow never came so I took matters into my own hands and took her to a respite bed in a care home - Mental Health then agreed that the care home was the best place and a DOLS was applied for.
Dont let SS bully you if I had refused to do anything when they first decided she had capacity four months down the line would not have happened.
