I don’t think you need to plan everything on a time line (just know your general goals and directions), but what about working on compiling your divrei Torah while you’re learning in yeshiva?
You’d have amazing people around you to give you thoughts and ideas about it (and it could really serve to shape your religious perspective. You’d be sharing with rabbonim your Torah thoughts and they can help reinforce, shape and solidify your thinking in a mainstream Torah way.
Once you’re in that environment, have made connections to rabbonim that you admire and who can understand you, you could consult as to what course of action should follow your time in yeshiva (semicha, nursing, dating, etc).
