Are you an LPN? I would get my RN (in as little as a year and often can be studied on your own time and just the tests taken; my next door neighbor did that but there are other work/study options if you already have a science/nursing background) and then think about what you wanted beyond that when you got there. There are psychiatric nurse practitioners and other sorts of counseling/psychology-related nursing fields but with a bit more education you could probably get different sorts of jobs to explore what you really liked most for a bit before you chose additional schooling after that?
