The 51-year-old shared: “It feels like someone came in and confiscated my brain and tied my hands behind my back to just watch and see life go by without me participating in it.”
Last January, Foster told Global’s The Morning Show she lost the ability to read and write.
Foster was diagnosed with Neuroborreliosis, a central nervous system disorder caused by Lyme disease, three years ago. She said antibiotics and holistic treatments enabled her achieve about 60 per cent recovery — but she suffered a relapse in December.
“I have not been able to find my way back,” she said.
Foster has been married since 2011 to David Foster and has three teenage children from a previous marriage.
She said she has made it her life mission to find a cure for Lyme disease.
“As tired and hopeless as I feel at times, I have an undeniable spirit that will continue to fight and travel the world until I have the proper answers,” reads the blog entry.
She acknowledged the “unwavering support” of her husband and children and encouraged fans to be nice to others.
“As a human being battling this everyday invisible disability, I ask you to join me in making a kind gesture to someone every day, because everyone you meet is fighting a battle you know nothing about,” said Foster. “So your kindness goes a long way, and together we can make a real difference in someone’s day.”
