I actually found that working was how I escaped to cope with my mental problems. Outside of work is where I really broke down and had problems. For me, work was a place with rules, structure, metric values for knowing if I was doing a good job or not. I liked it. Perhaps the types of jobs you are seeking aren't right for you. Perhaps you need to look at the purpose of a job differently. See it as an escape from the rest of the world. Just play by a set of rule predefined for you and things will be fine. I successfully worked as a marketing manager for over 15 years employing that type of philosophy. I'm on disability right now and am OK with that, but it wasn't because of my job. It was because of my illness.
