Starting new college with bad anxiety

I haven’t been diagnosed with anxiety/social anxiety and I know you shouldn’t really self-diagnose but I am certain that I have it. I finished secondary school a few months ago so I’m starting a new college in less than 2 weeks and I am terrified. I’m not going to know anyone and I physically can’t talk to people I don’t know so I don’t know how I’m gonna make any friends. I absolutely hate social situations they make me so uncomfortable and I feel like crying. When I try and talk to people I feel like I just embarrass myself and I’m sooooo unbelievably insecure and self conscious I actually feel like the ugliest girl in the world and I just wanna hide my face and I feel awful about myself constantly. When I talk to people I just feel like they’re staring at my face and judging me and thinking about how ugly and vile I am. I don’t know how I’m going to cope and I’m almost crying right now just thinking about it😭 does anyone have any advice??
