Look, I was right where you are: I had graduated with my BA in psych but didn't want to go for my PhD. I wanted to become a nurse but didn't want to backtrack too far, and I was 26 and didn't want to waste any time about it. Due to some personal things that occurred while I was in school, my GPA wasn't stellar and at one point I was even on academic probation, but I got it together. I found a BSN program, took a year of science prerequisites and have had my RN for 7 years now. Keep applying to schools. If there's one you are particularly interested in, contact someone there and ask about a meeting. We are going to really need dedicated nurses over the next few decades and I'd hate to see you get discouraged so easily. There's plenty of benefit to having a background in psych as well, even if you aren't financially compensated in an obvious manner.
