Go into something that you want to do, not because this job or that will give me more money down the line. If you aren't happy with it, then your aren't going to be happy down the line.....
I suggest that you try shadowing a nurse for a couple of days at different facilities, and the same thing with an occupational therapist. That is the only way that you are going to find out which you prefer...........
Sorry, but no one can make your decision for you..........
