Slap to the face, Punch to the gut

It started my last semester of college.
I applied and got an internship with my university as the 'photojournalist' for university communications. In essence, I went to all the events/talks/shows on campus and photographed the people/events/shows.
You won't see them here because, well, they're not part of my artistic practice. This internship was to see/teach me how to work in non-artistic photography.
At this internship, I was told upfront that I would get credit and be able to build a portfolio.

Only later have I learned that this program, along with practically every other program the school does, was a bucket of lies.

I have no credit
I have no ability to prove what I took is what I took
I have no portfolio because I fear that if I use the images I took, I'll be sued. [it may be irrational, but I don't want to risk it]
And to top it all off, the photo-essay I wrote up was taken by my boss and put under her name and not mine

My photos have been used for articles, a couple of publications, profile imagery, and blog stories. Some of the photos I took at events before I was even in the internship have been used for other things. One example is a photo I took during an event was used for the school planner. How did they get it? Off a facebook friends page.

I didn't know that every picture I have taken at this school can be used for their gain.

Don't get me wrong, I loved my education I got there, my professors are awesome people. It's the politics and administrative parts I really am beginning to hate.

Now, I've graduated, I'm looking for work with some relation to the artistic field. It's that much harder to get said work because my internship shows no work by me. Thankfully I have a job working for my father, but I would like to be a little bit fiscally independent from my family. And at this rate, I'll be working for my father for a while yet.

Is it that hard to add "Photo by X" next to an image? I seriously doubt people will die if that happens.
I just want credit. I want it for the ability to get work in the photography field.

I don't know what to do because I'm pretty sure walking in and demanding credit will not reflect well on my character.

TL;DR - give credit where credit is due. It's wrong to believe that a photographer is worth less than a reporter.
