Hi Gary, your friend will need lots of support, 7 years of being told what time to eat, what time to get up and what time to go to bed, its hard but with help from a good friend,however it may take years to get over it.
I once took a murderess back to Durham prison, it was a lot better than where she had been staying for 6 months while the trial took place, as jails go its one of the better ones.
Jail is not supposed to be a punishment, the punishment is removal from society, this is sometimes very hard to deal with.
Good luck with your friend, I hope her time can be gotten over,sadly it will never be forgotten
