I think that the situation of women in prison in movies is often shown as worse than it is in real life. I think in real life the boredom is the real problem.
Not that prison is a complete walk in the park, by any means. I know that pregnant women in prison, in particular, face all kinds of problems. Stress and pregnancy don't mix.
And any time you have one person subjected to another person's near total authority you are going to get problems.
But generally I think that there are more problems after prison than during it. People who have not been permitted to work for months at a time and who have to admit to a prison sentence every time they apply for a job aren't exactly going to be at the head of the cue when it comes to job applications.
It wouldn't be the prison sentence that would bother me so much as the conviction. It could ruin the rest of your life.
