School Options?

So, I am a new member here, but I have read alot of information and posts about different things on this site for awhile. My mom is an LPN, working on her RN right now, and I am 21. I have an EMT license, and I work in a mental health site for a human support services agency. I am considering school for this next year, but I am very conflicted as to what I should choose. I love all things mental health and psychology wise, but I don't just want to do the normal psychology degree ya know? So i was thinking a Human Services degree, which would be counseling, social work and all of that mixed in. Okay, but now, I have met two nurses, one, the RN who supervises our sites all things med and training wise, and a Nurse Practitioner, who I talked with and got me interested in that field. But for that, I would need an RN license, which would cancel out the human services degree, and then I would have to get the masters for the nurse practitioner degree, which I wouldn't be able to do a masters in counseling -- which is what I would really like to do. Short end, I'm not sure which path. But the underlying question I have, is, would it be cheaper, to get an LPN license, and then get an Rn-BSN degree? Or would it be better to just go to the Rn-BSN off the bat? Thank you all for whoever reads and actually responds, haha.
