I too was a psychology major and struggled through classes like abnormal psychology. Relating to the topics, illnesses, symptoms and such is common. But, it is especially hard when I really did experience and relate to the illnesses and symptoms. I had to kinda distance myself from the material and treat it as a class—not therapy. I kinda temporarily boxed my emotions and focused on the class as a student—not as a patient. If that makes sense. I suspect it is similar to what a therapist has to go through when they relate to what a client is talking about. Feel free to PM me if you ever want to chat about it.
