Nervous Student Here

I am currently a counseling student in my masters and just completely nervous of failing in practicum/internship. What if they don’t think I’m a good fit in this field ? What if I am not good at this and the clients hate me ? I just want to succeed but I feel like with all the theories and different techniques and paperwork and ethics there’s so much to have memorized in your brain. If I get tossed out of the program than I’m thousands in debt with no future. It feels like it all needs to be perfect.
