Case #3: The Case of Mark 
Mark is a 34 year old single Asian American man who lives with his mother and works as an 
accountant. He is seeking treatment because he is very unhappy after having broken up with his 
girlfriend over three weeks ago. His mother had disapproved of his marriage plans, ostensibly 
because the woman was of a different religion. Mark felt trapped and forced to choose between 
his mother and his girlfriend, and because “blood is thicker than water,” he had decided not to go 
against his mother’s wishes. Nonetheless, he is angry at himself and at her and believes she will 
never let him marry and is possessively hanging on to him. She is a very domineering woman 
who has always “told me what to do,” says Mark. He is afraid of “making waves” with her 
because she might throw him out of the house and he would have to fend for himself. Although 
he views himself as being weak, he also says that he really loves his mother and “she’s been there 
when no one else was.” He vacillates and thinks that she may have been right about his 
girlfriend. 
Mark works at a job that is several grades below what his education and skills would allow him 
to do. He has turned down promotions because he didn’t want to take on the added responsibility 
and was afraid to supervise other people, for fear of offending them. He also didn’t want to have 
to work independently on projects. 

He has two close friends from childhood and meets with one or the other of them every day for 
lunch. If either friend misses a day for any reason he feels “lost” and gets worried his friend 
doesn’t like him anymore. 

 

Since he broke up with his girlfriend he has been feeling very despondent. He’s had difficulty 
getting enough sleep almost every night. He’s also been losing weight because he doesn’t feel 
like eating that much. This is of some concern because Mark has been diabetic since childhood 
and although he generally does a good job of monitoring his blood sugar level and administering 
insulin, not eating regularly makes it harder for him to maintain an even level. Mark complains 
because his mother then gets especially worried about him and becomes more intrusive. He 
admits that the reason he stays at home with his mother because of his diabetes and his fear that 
it would get way out of control if he did not have his mother overseeing and monitoring his 
diabetes management. 

Mark used to play cards with his friends on Friday night but he has skipped the last two weeks to 
stay home with his mother. “I just don’t have the energy to go out.” He still is functioning all 
right at work but he finds it increasingly difficult to make decisions whether at work or not. 
“Even about small things, like what kind of bread to buy. I just ask Mom what she wants.” He 
denies any suicidal ideation but reports that this is the second time he has felt this down. “Two 
years ago, I was going out with another girl and the same thing happened. As soon as Mom met 
her, it was like that was it–they hated each other. Mom would never let me hear the end of it, so 
I just stopped calling Martha. But she probably wasn’t right for me either.” He says, “After that I 
could barely get out of bed in the morning for about four months. But then I just gradually got 
over it.”
