The Shrink Is In (2001) on Netflix

Plot summary

Samantha Crumb writes about travel, and her boyfriend breaks up with her just before a trip. On the plane she has a breakdown, pulls the emergency exit cord, and is ordered into therapy. She starts eavesdropping on her neighbor, who is having a rough time with his girlfriend. Then her psychiatrist, Dr. Louise Rosenberg, suffers a breakdown of her own, and Samantha takes her to the hospital. The staff say someone must tell the doctor's patients she is unavailable, and with no secretary Samantha makes those calls. Her neighbor Michael comes looking for the doctor and, having never met the real Dr. Rosenberg, takes Samantha for her. She does not correct him, hoping he will break up with his girlfriend, and when a magazine salesman named Henry Popopolis comes to the office, she treats him as well.
