Hi Newbie!!!
I just graduated in Decemeber with a BA in Psychology. I don't regret it at all. Like you, I've wanted to major in Psychology since at least my senior year in high school, possibly since the eighth grade. It is true that there is no money in it until you receive your PhD, but if that's where your heart is then that is what you should study. Also, there are several options you can take advantage of, such as double majoring in Psychology and Business, or simply majoring in Psychology then receiving your Master's in Industrial Organizational Psychology. This area of psychology can/will bring you the bucks. It's bringing together Psychology and Business. You could major in Business, minor in Psychology. There are ways to follow your heart and secure your future.
Good Luck!!!
ps...I know the struggle of wanting to follow your heart and please your parents. Hang in there...
