When I was at college I got no diagnosis and no help what so ever with my illness. As a result I failed and was blamed.
Later when I developed moderate to severe ME my GP refused to help me with my housing application which would have prevented me getting permanently worse. The house I was living in was very unsuited to my needs. It was noisy, dusty (I have a severe dust allergy), mouldy, had a steep flight of stairs (I live in a bungalow now), two big steps to the bathroom, and parents who believed there was nothing wrong with me, and even refused to let carers in to help me. That place crippled me. My doctor even refused to talk to my parents to tell them I was seriously ill, and he refused a home visit when I was mostly bed bound with bad abdominal pain and blood on my poo. Social services said they couldn't help without a doctor's note.
