Hi. It really depends on if you think you can stick at however many years of training and then however many years in a job you're not sure you want. Would a course in fashion really help you to get a job in that field or is it something you think you could get into without training? I did a film degree because it was something I love but I never thought about what would happen at the end of it, and since finishing I have never used it. I was going to change to psychology at the time but decided to stick with film, and now am doing another degree....in psychology. I don't regret my first degree though because it helped make me who I am and it was right at the time. I guess what I am saying is that you do need to think about what will happen at the end of it so you are not wasting your time and money, but at the same time it has to be something you enjoy enough to stick at. Do you actually want to be a nurse? If you don't then there might be the danger of you giving up because your heart isn't in it and then it will still be a waste of time. I'm sorry I can't help more or give you an answer, obviously that has to be your decision. Good luck though, and be happy.
