Libby Meyers was first diagnosed with ME in 2000 and by 2002 she was bed-bound.
A Dorset woman with severe ME who has been unable to leave her bed for eight years has been "left to rot" by the NHS, her family has said.
Libby Meyers, 62, is in a nursing home in Charlton Down near Dorchester but her family want her to be treated at a specialist NHS centre in Essex.
Her husband and daughter have appealed three times but their applications have been rejected by NHS Dorset.
In a letter to the trust, Oliver Letwin, MP for West Dorset, said he was "dismayed" that attempts by Mr Meyers to obtain proper treatment had failed.
