By the time you'd be ready for CRNA school, you'll have experienced quite a bit as an RN. If you don't like the idea of being a nurse, I can't imagine you'd make it to CRNA anyway. So, the first question you need to ask is... can you think of some pre-requisite specialty that you might enjoy?
I had been in a hospital all of about 3 times before I decided I wanted to go to nursing school... I was scared to DEATH when clinicals started and probably felt more out of place than anyone in my entire class. I'm only a 2nd year student and I've already grown to love it more than I thought I would, and I'm at the top of my clinical group.
The point is, if you think you would be interested in some aspect of nursing, by all means do it! Once you get your BSN your options are limitless. Perhaps you need to examine all of the different specialties that are out there and decide what you'd like to do on your path towards CRNA.
Here's a good place to start:

Good luck!
