I was really sick': Yolanda Foster on how she realised she had Lyme disease as she watched herself rowing on Real Housewives

Unable to think straight, form sentences or function properly, Yolanda Foster knew something was wrong.
But it was not until a colossal fight with her Real Housewives of Beverly Hills co-star, Taylor Armstrong, that she realised she needed medical help.

'The Lyme disease had so severely affected my brain functioning that it was extremely hard for me to think, form sentences, and stay focused.
