I'm torn between heading towards becoming a Physical Therapist, Nurse, or a Pharmacist... I need some advice on what to follow. Any suggestions?

So, I know I have time since I’m a freshman in college, but I hate not having at least some sort of a line towards my future at least as a suggestion/ pathway… At this moment I’m so indecisive about what the heck to lean towards. I change my mind one day from pharmacy, to therapy, to nursing, and I have absolutely no idea whats going on. I’ve shadowed each profession, and even the lower ones of each category, yet i still can’t figure it out.
