My bachelor project focuses on depression, the widespread illness that 15-20% of the population suffer from at least once in their lifetime. Depression is a serious illness that requires treatment, but despite being so common, it still remains a taboo. As it is often invisible to outsiders, understanding is lacking. Therefore, a lot of people, who suffer from depression, don’t seek professional help and their illness remains untreated. It was my goal to show the illness as it is perceived by an individual woman, who has been suffering from severe depression for the past six years. Thanks to therapy and the right medication she learned to cope with her illness and is now able to speak about it openly. Through a combination of self-developed imagery and diary-like entries I aimed to convey her subjective perception of the illness and her respective mood throughout it. I have divided the stages of her depression into individual chapters that follow the course of time and differ in their visual language. Certain chapters cover the side effects of different antidepressants, others the feelings and thoughts she had in different stages of her life. In close collaboration with her I developed pictoral worlds in a 3D-program, as artificiality, spatial depth and the play of light and darkness play a big role in depression, as well as in 3D-space.
