A very good light hearted one is "What about Bob?" with Bill Murray and Richard Dreyfuss, Bob (Murray) is agoraphobic with pa's, Dreyfuss (his pysch) is his new doctor, but leaves town for a month on vacation with his family. Bob freaks when he learns that he will be gone, all the What ifs, during that time, he needs to be with able to get in touch with his doctor and not the one on standby, he goes to extremes to reach him and winds up on his doorstep.
In his first visit to Dreyfuss as a patient, is classic as Bill Murray's character is phobic of elevators and learns that Dreyfuss office is on the 20th floor or something like that, which he questions in his mind, how the heck a doctor that treats this disorder cant get an office on the first floor! Then you see him climbing stair after stair, gets into the waiting room, he is short of breath, in a sweat, and checking his pulse, he is in an attack just trying to get to his office.
I highly recommend this movie!!
