Internship making me regret degree

I don’t do much besides admin work like mailing, scanning, and boxing things up. I do have a small caseload of clients but they are phone calls only and rarely answer the phone. This work is not interesting and my field instructor is not very supportive. I haven’t really learned any skills; most of this is just common sense. This is very mind-numbing and not rewarding. I’m nervous my next internship will be worse or this will not be a very fulfilling career. Hoping someone can relate and was able to have a good second year internship instead.
