<human>: I am returning to my university for half of a 5th year.  During my time here at school I held a position which inadvertently had me working 10+ hours that I would get paid for, which I did; without question.  I worked really hard to have everything work at my job.  At the end of this year I decided to leave the position and apply to step down to a front desk position.

About a month ago, I was brought into my bosses office and was reamed for other people doing my job, and not being prepared for events we were putting on.  In actuality people began taking care of all my duties to try and impress my current boss, so they would get hired, and we weren't prepared to host the events because my boss kept putting off hiring new staff and volunteers (something which I cannot do).  I sort of reamed into my boss, and brought up everything that I thought was going wrong.

Anyway, this week they were hiring for the new positions and I decided it would be best if I didn't apply for the position, seeing as I had just essentially told my boss she wasn't doing her job effectively enough for me to do mine.  But she approached me and had set aside an interview time for me anyway (before I had submitted an application or resume), telling me she thought I could still be really helpful behind the desk, ushering in the new student staff.  So I killed the interview, and was even told during the interview by the panel that I was doing very well.

Today my boss walked up to me while at work, in front of my peers and some friends saying I didn't get the job.

**What The Fuck.**

How to I go into work the rest of the year knowing that I was set up in this interview so that they could tell me no.  How can I continue working for this department after I was set up to fail like that.  I have given 3 years of my college career to help this department and they cant keep me on to help the department I have skipped classes, practices, and even numerous dates for.

Please tell me Reddit, how do I face that tomorrow?

Can you summarize the given text in a few sentences?
<bot>: I was asked to interview for a position which I have can be of incredible assistance to the incoming staff, only to be flat out denied, publicly.*
