“Real Housewives of Beverly Hills” star Yolanda Foster spoke up about her struggle with Lyme disease in a new blog post on BravoTV.com. She used to post regularly on the site, but started this letter with an apology to fans: “I would like to apologize for my lousy participation in the blogging department at the moment. Although writing is usually my favorite thing to do, I unfortunately have lost the ability to do so in an intelligent matter at this time.”

She then described her struggle to do everyday tasks: “I have lost the ability to read, write, or even watch TV, because I can’t process information or any stimulation for that matter. 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.”

Foster was diagnosed with Lyme disease in 2012 and though it has remained nearly absent from this season of “Real Housewives,” her illness was always a small part of her storyline. Foster often shares updates on her health via Twitter and Instagram and aims to educate the public about Lyme Disease. Read her full blog post over at BravoTV.com.
