But I just don’t know what to do with this fucking degree information wise.
You sound pretty mild about all of it. Why'd you pick the major you did if you don't really care about it as a discipline or as a potential career avenue?
I don't really understand why you'd spend 4 years twiddling your thumbs rather than taking advantage of every possible opportunity to learn and grow.
If you have one year left, I'd urge you to make the most of it by engaging your mind in your courses/subject matter/something rather than passively learning facts and coasting along. Find some fire, whether that's in courses for your major, doing research with a faculty member, exploring something else completely, or investigating jobs or opportunities to do something cool. Why not? Challenge is good for you. As is personal ambition. Working to create and pursuing concrete goals can also help general anxiety (of course that can vary, but a lot of people feel more solid and confident, and have less of a tendency to spin on general or specific worries, when they are busy and engaged).
The point of all that is to say school years are full of stimulation and opportunities to enrich yourself and/or find direction. If you aren't learning much, that's a travesty, and you're not living the life you could be - a life that is stimulating and interesting and more than passing time.
It's not. It's 100% not an individual issue. Construction project managers come in fresh knowing how to make a simple schedule or use a budget, but have no working knowledge on how to do the single most important thing: identify, manage, eliminate, and transfer risk. They don't know how to read and understand a contract, but they sure can take good meeting notes.
Fresh civies aren't much better.
School is about foundational learning. Application can be learned a bit in internships, projects, summer or part-time jobs, fieldwork requirements, etc., but every new/junior employee is going to be raw. Which is one reason to knock your schoolwork/grades out of the park - so you can get to the best first job you can and be trained well.
