Coping with Autism in older age

I’m married 32 years my husband was diagnosed 5 years ago but we knew for many years . Over the last two years things have got worse. He can’t cope without regular patterns, increased anxiety struggles to work support is limited and changeable. Problems with  His short term memory and agitation has increased but GP pays lip service to it.

I’m struggling to maintain my health and cope. Yet few people outside as he doesnt have friends nor wants any see him presenting this way. Its all saved for me at home
