'I'm Going Slightly Mad' follows Aaron Magro, a college student trying to adjust as life throws obstacle after obstacle at him. Balancing his studies, a job, and friends begins to wear on him, and as he finds himself resenting every unneeded turn of events, he also finds his resolve weakening. He's running out of steam, and heading for a breakdown, and he isn't sure how much longer he can hold out. With support from his police officer friend, Lucas, who tends to hinder as much as he helps, he keeps pushing through, even as life keeps throwing him curveballs, such as love interests he never would've expected, broken bones, and dangerous rivalries. Only adding to his problems is his older brother, Caleb, who is causing trouble for their parents with a sudden visit, and the reasons behind his sudden return may change Aaron's attitude completely. College is turning out to be very interesting, in a way Aaron doesn't quite appreciate.
