I have not pursued a degree in psychology, but read numerous books on the subject and learned much from a published sibling who pursued a phd in psychology. I found it helpful in dealing with my depression (and other behaviors/emotions) and understanding its mechanisms. Though, you should be wary of labeling yourself with what you learn, or entertaining the illusion that one can analyse oneself. Psychology is such an important subject it merits attention even if, however unlikely, you would derive no benefit.
