I double majored in English and psychology, with a degree in high-school education. So, I did have an option to teach when I graduated. I applied to grad schools in English (writing specifically) and in psychology. I got into the grad school I wanted to get into in psychology, and I earned a Ph.D. I taught psychology in various colleges and universities for a number of years.

I agree that there's not much opportunity in a psychology field with just a Bachelor's degree. And psychology is not a major for education, since very few high schools would offer such a class. I did teach intro psych classes in two high schools for one term, but it was as an adjunct college professor.

I do need to ask you this question: How are your grades? Do remember that getting into a decent grad school does require a respectable G.P.A. However, as other folks have said, Educational Psychology might be a possibility. It's a research degree, however. If you actually wanted to work in a school system, then you might consider School Psychology.

I definitely encourage you to go to a career counseling center, research the requirements for various grad programs, and even talk to some folks who actually work in fields you might be interested in.

What area of psychology interests you the most? You would need to pick a certain area to go to grad school in, of course. Could it possibly be Ed Psych or School Psych? When you took the intro psych class, which I assume you did, what chapters in the textbook were the most appealing to you?
