Her symptoms include bilateral hearing loss, oscillopsia (jumping vision), and imbalance. Lynn says that if she had been given the correct diagnosis in the beginning, they might have been able to save her hearing. "This disease has robbed me of my hearing, my career as high school biology teacher, my ability to walk, to drive, and so many things," says Lynn. "But I refuse to let it rob me of my joy and quality of life."

Darcy worked several years in a State Disability Services Department processing and making decisions on Social Security disability claims. She went on to work for the Social Security Administration processing claims for disability and retirement. In 2005 she had her first vertigo episode, which led to a vestibular journey that continues today. Initially diagnosed with Meniere's Disease, testing also showed an Enlarged Vestibular Aqueduct and eventually an Acoustic Neuroma. After surgery she lost all of her hearing. She now has bilateral cochlear implants. It was life changing not returning to a job she loved and instead going full circle in the disability process; filing for her own benefits. While there were many hard days of not feeling well, and with added diagnoses of Vestibular Migraine, PPPD, as well as additional chronic illnesses, she saw there was still so much joy to be found in every day life, even while being sick. Determined to continue to find a way to help and encourage others, she became involved in patient advocacy. She is currently an Ambassador for VeDA and is serving on the DEI Committee.
