Of course, studying in a specialty that you do not need is a waste of time. But you should never jump to conclusions. I would advise you to read some essays about Frankenstein. You will be able to read interesting information for you, such as mixed emotions. Perhaps the same thing happens to you when you want to change your specialty. You can read it here https://happyessays.com/free-essays/frankenstein/ I hope and think that it will help you understand yourself and you will draw the right conclusions for yourself. Also, at the same time, you will be able to understand how to write works correctly. I think your life will be able to change and everything will be fine.
