When not even the student advocate will stand up for you, who do you turn to?

There's a story behind this, of course, but I am feeling so defeated right now and am trying so hard to not dissolve into a puddle of "Nothing matters" that I don't have anything left in me to begin to explain yet. I was always obliquely aware of the power dynamics of professor and student, but until I was that student..

Suffice to say, I could not feel more powerless than I do right now.

Edit: gifs would be appreciated. I'm at a really low point right now.
