Can anxiety/stress cause such symptoms?

I'm not sure if anxiety can affect you to this extent, which is why I'm curious. It's not the first time I feel symptoms of a fever on the inside but I am as cold as a corpse on the outside. It first happened when I was feeling anxious about my final exams; two days before going to write them, I began to feel really cold even though I was burning up on the inside. I had chills and a bit of nausea, but I didn't have a fever.

I was to find out that after I finished my finals the symptoms were gone. I thought I just made it up in my mind since I'm always being called dramatic or told I'm overreacting.

The second time has happened today. I've been dreading going back to school on wednesday since I also experince symptoms of social anxiety. I'm constantly worried I'll mess something up or do something stupid like the last couple of years to make others judge me. I'm also too useless to fill out a form to see a counsellor, and it worries me because I've been overthinking about the fact that I never signed up for physics 20. Where the internal fever came again was today when my wifi kicked me out and I reset my chromebook. It needed wifi to be set up again, but we couldn't fix the router. I began panicking thinking about what I was going to do if classes began the day after tomorrow.

Medication doesn't seem to help and I can't think of any breathing excercizes that can help me.
