Marjane is depressed because she's still hiding what happened during her time in Vienna. She wants people to understand her, but she doesn't want to tell them what she lived through.
A friend invites her skiing, so she goes and has fun.
Well, she has fun until she admits that she's had sex and one of her friends calls her a whore. Even sitting in front of a roaring fire with a mug of hot chocolate on top of a snow-covered mountain can't fix that.
Back home, Marjane goes to therapy. She is prescribed medication.
The medication prevents her from feeling anything except like she's "in a trance" (31.33).
