It really does help to just drive to some place on weekends and walk through nature, thou it doesnt even have to be nature it can be some village you havent been to or some city youve never been interested in. At first it might seem like a bad idea but literally like in the manga nearing the end you feel much better especially if youve walked plenty or hiked a bit, the chemicals inside give such a relaxing mood boost. So I think this is acurate and also really effin nice, I like this big gal.
