I'm a firm believer that whatever a problem may be, the solution for it lies in a book. A theory I apply to every aspect of my life, from bad breakups to important career decisions, the power reading has to affect my life has in profound ways has even proven itself in the books that help me through my depression. Without the help of one very important TBR pile, I don't know how I would have gotten through some of my darkest days.
I have suffered from depression off and on since I was a teenage, and the struggle to cope with it has dominated a lot of my adult life. There are the days where my depression is just a slight, lingering feeling in the bottom of my stomach that I can mostly ignore. But more often, there are days where it's a cloud that consumes everything and everyone around me, a cloud that won't part for anyone or anything.
I should point out that reading is not a cure for depression, but it can be a kind of coping mechanism for its symptoms. On those really bad days, the days I can't seem to even get out of bed, the only place I'm able to find solace is on my bookshelf.
