Still discovering myself...

I've been having a hard time figuring out what I want to do for the rest of my life. I'm 20, I started college right out of high school and in a year I will have my bachelor's degree in psychology. The only problem is that my true passion is photography, but I'm afraid that if I pursue that I will not make enough money to have a nice home and decent finances to support that family I want to have. I'm anxious about grad school and I'm not sure it's the right option for me. Any thoughts or opinions? I just don't know what's right for me, I'm hoping to gain some insight from the beautiful ladies on this site.
