That is a lot of pressure to put on a single reading, much less a single reader. Paths in life can change and sometimes that is for the better. I think if you had put more energy in, you could've possibly "realized" the reading, but in this sense would your true intent been correct in this case considering the actual outcome? You ended up on higher ground having explored this possible path... so in a way, it did put you where you needed to go. It eliminated one fork to send you down another.
Really, it's a big task to ask ourselves to pick a path. Especially when we're young, we're told we should pick a degree and stick with it. It can be confusing to think--well am I going this direction because my culture/society suggested I should go this direction or I am meant a different path? A lot of times it feels like we're the mouse in the maze following the cheese. Did we choose because we were forced to choose or did we really choose for ourselves? That can put a lot of anxiety on the shoulder's of a graduate, even if their initial outlook in life was extremely positive. It's the actual staring at the door that creates mixed feelings... which might be why you asked the feeling to begin with, to alleviate or otherwise sift through the cognitive dissonance. I think plenty common to have someone nearly done with a program consider changing the program altogether or going to a different field. It's happened to a few of my friends. Some end up going back to their field or they do find a new passion. I guess it just depends on the individual.
I had a friend in high school was stressing about picking his potential career. Too young to really make a firm decision, but I gave my intuitive thoughts (which he didn't know was intuition)... I told him, he should consider being a personal trainer. No real reason why I picked this except his aura said this. He was extremely excited about the prospect, a guy that just doesn't get excited. He was like oh wow, thank you so much. That sounds perfect!...
Did it matter if he went with personal training and fulfilled that prophecy? No. It mattered he saw within himself some possibility he could find a potential path. It put him in the driver's seat instead of him stuck in the web of his own emotions, questioning his decision making and his life purpose. He was now making decisions and learning to search for his own personal possibilities rather than being held down by what others expected of him. After that, he was all smiles when he saw me, so I think that it served the purpose, which was to motivate him to take control of his life... like many of us eventually have to do.
A lot of us have a lot of pressure put on us from the day we are born. Either to fulfill some stereotype, some familial aspiration, or even just to meet society's expectations. Either way, that can really get in the way of sorting our true intent's... which is something I think is really key to making divination work for you rather than against your personal truth(s).
