“I refer to my illness as the devil because it’s destroyed everything,” she says. “I struggle with relationships, trust. I can’t keep a job. I haven’t been able to receive my high school diploma. I haven’t got my driver’s license.”

The 27-year-old also admits that she tells “a lot” of lies. “I lied about stealing, where I was going, drug use, taking money, taking my other family member’s medication,” she admits. “I don’t mean to steal; it’s just a part of my mental illness.”

Courtney says that her family “doesn’t get” her and treats her like the black sheep. “My mom thinks I use my illness as an excuse. My mom really gets on my nerves, and she triggered my bipolar. I feel like my dad’s so disappointed in me,” she says. “I want a relationship with my family, but they just need to give me a chance.”
