You're smart for getting a little med surg experience under your belt first. I didn't and I knew I'd lose so many skills, but I loved psych and didn't care.
Don't forget--- a hospital isn't the only place to practice psych nursing. There are psychiatrists that have a nurse working by their sides, homecare psych nursing, and treatment programs. I work in a residential treatment facility. We usually get people from the hospital. Sometimes they're ready to be out, sometimes not. It's very rewarding, very interesting, and just plain fabulous. I am the only nurse there--- all of my coworkers have psych degrees. It's usually a bit more low key than a psych unit in a hospital, and I don't have to deal with mandatory OT, being short, and cruddy things that poor floor nurses have to deal with sometimes.
So explore your options. There are quite a few.
