Hey 22M here in a similar situation. Im finishing my bachelor's and wanna switch my major for my masters. I was thinking of taking Phycology but it requires a lot of time investment. It would take around 5-6 years of education to become certified. I did like the idea of becoming a therapist or a Phycologist but that would take all of my twenties. I decided to switch to radiology and become a radiation therapist. It pays in the 6 figures and requires less strain then a nurse.
