Welcome to MacInsiders!
Glad to see you in the forums. Congrats on choosing McMaster!
I was nervous as well coming to uni for the first time, I think everyone is in some way. You're not alone.

I also HIGHLY HIGHLY recommend you register for HORIZONS, it is a conference that takes place at McMaster over the summer for incoming first-year students and helps you meet people before school starts, and feel more confident and comfortable on campus. It helped me a lot.
