Making new friends at a new school

So I have general anxiety and social anxiety and i'm about to start TAFE soon. It's only one class a week for 5 hours but i'm stressing out so much about making friends. I had absolutly no friends for the first year of high school and it was once of the hardest years in my life because I can't cope with loneliness. Sometimes, when I try to talk to people I freeze up and literally can't get a word out and it's really annoying. How do I make friends at this new place? It goes for 2 years and I really don't want to be alone for that long. Thanks for reading :)
