Lydiа аnd her fiаncé, Marcо, cоme tо counseling together. Lydia quickly says she does not know why Marco has made her come since everything is so good. She reports she has been “so completely happy” for about two weeks, and that though she often gets depressed, nothing can bring her down right now. Lydia has says she has only needed a few hours of sleep each night, so she has been getting up early to exercise, decorate the house, and learn a new language. At work she says she has felt extremely productive and she has been volunteering for every new job since she has so much energy. Lydia talks in an almost pressured speech throughout the session and constantly changes the subject. When she steps outside to call her mom with a new idea about how to organize her parent’s home, Marco shares that despite her indications that all is going well, she has been spending excessive money on her decorating projects for herself and others to the point of maxing out two credit cards in the past week. Also, Lydia’s boss who is also a friend of Marco let him know that she is in danger of losing her job because she has volunteered for everything but can’t seem to finish any projects. Which diagnosis is most likely for Lydia?
