It is. I assumed that she was starving herself or purging what she does eat (I can't imagine that binging in county is possible, but I wouldn't really know), and the powers that be in jail interpreted that behavior as self-harm/suicide attempts.
I remember an episode of Intervention in which the addict was an Indian man who was adopted by a Mormon family and they lived in small-town Utah. He was the only person of color, like, around. The family was VERY white (fair, blond) and the Indian man's skin was dark. Growing up, the family kept insisting that the Indian boy was "just like them" and he was like, but I can SEE that I'm not; my skin is brown and yours isn't. And of course what the family meant was that they loved him as much as they loved their bio kids but what he wanted was for them to acknowledge that he was, in fact, different, and they just staunchly refused to do it. And it fucked him up and he descended into addiction. And that was when the message he was getting was "we don't see color [which is part of why that message is so wrong]," not "white people are better than Black people," which is what Andrea seems to believe.
Andrea says Mormonism is a part of her history and that's not wrong (I would love to know how that happened), but she also seems to completely dismiss the idea that she and her kids are Black and there's a rich history there too.
