How bad is it at FMC Carswell women's prison she said that this is not the place to show emotion? Is it really that bad

Prison is no joke. Taking it seriously and showing no emotion is the right attitude. With a 30-month sentence, she is most likely assigned to the camp which is a minimum-security federal prison. It's probably never going to reach the level of the stuff you'd see on Orange Is the New Black. My advice, use this time to work on herself; exercise, read, and write letters home. This is not the worse situation she could be in.
