Shout it once. Shout it twice. Scream it from the mountaintops, and make sure that you are heard. Janine is not crazy. She's a victim of one of the most vicious aspects of human nature. For many, any sign of mental illness, any little flaw, is enough to justify complete abandonment. Nothing will send people running quite like a temporary lapse in sanity, which is what she went through. She had a difficult life--just her and her son up against the electric company, her landlord, and her boss. But she was making it, and she was doing alright, until she was abducted and thrown into cattle pens with groups of shrieking women.
The series ignores the things she saw, using the dark imagery sparingly, and only for a few minutes at a time. But there would've been two to three dozen others like her, unbathed, standing in cages with a single bucket, wearing the same clothes for days at a time. They would've stunk like sweat and unwashed flesh, and the sounds of suffering would've filled the air. Some were marched off to their deaths, begging while men shrieked at them, telling them to move faster. Others would plead, desperate to know what had happened to their children and loved ones. That's when Janine first lost touch.
We saw her rushed into a transport, yelling about how she was going to sue the guardians. Soon, she was being marched down the hall, into the basement of a repurposed high school. She was shown to a desk during one of Aunt Lydia's propaganda sessions, and she spoke out, saying, 'Welcome to the frickin' looney bin, huh?'
