Psychology is actually one of my majors, so I feel the need to dispute the common misconception that psychology graduates can't do anything with their degree. This is false in the sense that people say the degree itself is "useless". However, it's true in the sense that it's also true for a lot of other undergraduate majors, such as biology, chemistry, physics, neuroscience, and even math. (I mean, really, think about it. What can you do in these fields with only an undergraduate degree?) So it's not just a psychology thing - people just like to pick on it. The fact is that having an undergraduate degree does not guarantee you a job. Even getting one in a field that's currently evolving and needs lots of people right now, like engineering or computer science, doesn't guarantee you one. There's a reason that 5 year BS/MS engineering programs have become popular - because there's so many people out there vying for these positions, even so called "important" majors like computer science and engineering have to make themselves look better than their competition by showing that they're specialized in a field of their interest.

Getting a degree in psychology tells an unbiased (it's important to include that) employer that you likely have a good understanding of how humans think, act, and interact. It's a very useful degree and I should also note that it's very versatile. Personally, I'm pre-med, but other psychology majors and double majors have also gone onto law school, business school, etc... Basically, with a bachelors in psychology, you can basically work anywhere. To work in more specialized areas (such as social work or counseling/therapy), however, you would need a Master's. And of course, you'd need a PhD to legally call yourself a psychologist.

I agree with the person who suggested educational psychology. Educational pyschologists work in schools, which would be a plus for you, but they don't actually teach. So if that wouldn't be something you're interested in, why not double major or pursue a minor in one of the fields? (I'm not sure if education is offered as a minor, but some schools, like mine, allow students to design individually designed majors and minors.)

Overall, just find out what's best for you! I'm having to do the same thing right now while designing my double major and my dual degree that I'm pursuing. You have to do what makes you happy; not what pleases other people. Do what you can imagine doing everyday and thinking about how you can't wait to return the work next day. At that point, a job isn't even a job!
