A45-year-old woman, seen by her medical internist, has been experiencing fears that she may have a serious illness. She complains that after eating she experiences "a lot of gas" and abdominal pain, followed by diarrhea on occasion. Her heart at times seems to be beating rapidly, and she feels faint at times, has chest "discomfort," and wonders if she is having a heart attack. Multiple tests have identified only a mild irritable bowel syndrome. The woman's fears are not allayed by this. She makes repeated calls to be seen by her doctors as well as seeking consultation from other specialists. She insists that "there's something there" and believes the doctors are not taking her seriously.
Which of the following is the most likely diagnosis?
