Hi. You are certainly not alone. I am 41 and never knew, nor do I now know, what I "want to be" from a career perspective. I don't think I ever will, honestly. My attention span is so short with everything. I've been diagnosed as both Bipolar II and ADD, however I know that characteristics and symptoms can cross over. I know I am definitely Bipolar and suffer from depression very often. My attention and focus issues do not seem to be any better or worse at those times, however, I have noticed that they are affected by the meds I take for Bipolar. But they work, as does the Vyvanse for focus and attention. You may want to consider seeing another psychiatrist for a second opinion. I've never heard of there being a concern about Prozac making people hyper, but it can cause mania, which is not good.
