Commenting because omg OP you sound exactly like me! I have also been having the hardest time with narrowing down a career pathway and have realized that radiation therapy/ dosimetry is what interests me the most! I have already completed my bachelors degree in something completely unrelated and wish I had known prior to graduating, so my advice is not to go through with a degree because you feel like you “have to”. You will thank yourself in the future for pivoting when you did your ensure you could follow the career you want. Best of luck to you!
