I think Yolanda was/is ill but her story was so muddled. Like "I haven't driven in 3 years" or "I haven't ran in 2 years" yet there was footage of her doing both the previous year. It just didn't make sense to me and there's so many stories 'proving' why she was full of shit. For what reason? I don't know but I'm happy she's not on the show anymore.
