I have been hospitalized several times but usually when my reality does not sync with other people's reality. As well as being BPD, I am also schizoaffective and actually the last round of hospitalizations was because I was diagnosed as bipolar and ADD and the medications did not interact well together (I had delusions and hallucinations)

The one hospital I was in was overcrowded and was not really therapeutic. It was a privately run hospital and the focus was on making a profit. When I lost my insurance I was taken to the state run hospital and they had more therapy but it was with people who were not as functioning as you sound to be since your therapist wants you to check in after you finish finals.

Being hospitalized entails a loss of freedom that sometimes you don't realize until you are checked in. I am not fond of the hospital experience. If you smoke make sure the hospital you decide to use allows for smoking breaks.

Also, beware of making friends in the hospital because sometimes people are much different on the outside. I used to make friends but they were not the healthiest of friendships. I am friendly to others when I am there but I don't take the friendlyness outside anymore.

Good luck whatever you decide and I hope you do well on your finals.
