So weird. She fell asleep for like 3 years and then suddenly one day she just got up and went for a walk. Her husband was understandably concerned. Did they ever disclose what her diagnosis was?
She had (and still has) long COVID, which brought on ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) and MCAS (Mast Cell Activation Syndrome).
She wasn’t in a comma, but she also wasn’t just asleep for 3 years. Read the other comments here, she didn’t have the energy to do anything more than stay in bed to sleep and rest for the vast majority of the time.
