how do i make friends?

i'm 19 and out of high school entering my last semester of college. i didn't really have any friends during high school, people basically talk to me only during school hours and never reached out to me after graduation. im taking my classes online so i can avoid any potential awkward situations like presentations, public speaking, and just talking to people in general. i consider myself an introvert but i guess i could be an ambivert as well. my problem is that im very very awkward and i get nervous whenever someone talks to me whether it be online or in person. i can't keep any friendships due to this problem. how can i get over it? i can't exactly muster up any courage to go outside and try to talk. i get sweaty and visibly nervous whenever someone talks i speak 😭 i don't like going outside because i am paranoid of the potential danger i could face. i believe that most of these problems come from my fear of being perceived and seen but im not sure how to get over this fear. any tips?
