I hope you are in your twenties because it will take at least ten years realistically. You have to be a cna first and work a year as one. Social work is irrelevant. Then get into a two year rn program then get a bsn and that's two years. Or you can go the rn to psych np route to shave a year off your bsn. Meanwhile you better be smart or know all your drugs and conditions ahead of time. That stuff comes with time and experience. You are not going to see anyone just automatically know the side effects of finasteride. You have to give pills everyday see them, see the side effect, contraindications, talk to doctors, talk to pharmacists and then once you feel as if you know a lot (at least 3 years of experience) then you are ready. Buy yourself a neuroscience book read it twice. Then look at the psychnp program and buy the course books ahead of time read them and understand them. Live eat breathe psychiatry and work at psych unit if you can and then you are ready. Lets do some math cna 2 or 3 years rn 2 years then 3 experience while bsn is happening so thats 7 years of school minimum before you can even be ready. Good luck.
