Because ketamine has FDA approval, it can be prescribed legally by any physician. In fact, there are multiple private clinics advertising ketamine infusions, for a fee. But ketamine is still in an early stage of development for depression and OCD. I have my concerns and we need more evidence for its safe use in individuals suffering from these mental illnesses.
OCD afflicts Girls main character Hannah, who has been in remission for the better part of a decade. When it returns, we see a full blown relapse in all its eerie "glory." Hannah's first bout officially appeared in high school. We imagine her as a neurotic over-achiever with dreams of being a writer, who went overboard, as she became out of control with her desire to be in control.
