Getting insulted on rotations almost everyday and not being given a chance to practice

I'm an over thinker and sometimes react over sensitively to things happening around. I'm an undergraduate in my last year studying BS OPTOMETRY. Our university tends to send us ib different institutions for practice. But this institute has its own optometry program so its obvious who they'll be giving importance to. But since currently there's no rotation of their students they still are discriminating against us and not allowing us to practice while this is ho we are gonna learb and be better optometrist that can support the community but they just say bluntly in yhe face that students from my university are not allowed to touch instruments nor interact with patients.. Like we are in the last year of this degree n all they want us to do is observe!! This is making me go insane, I'm anxious, depressed, stressed.. Just don't want to go there anymore but attendance issue doesn't allow me to leave.. I just am over thinking these things for around 2 weeks, just don't know how to deal with those people n my low self esteem n over thinking that's being caused by the surrounding every single day
