making new friends

so i recently dropped out of college because i didn’t know what i wanted to major in, also stopped talking to any of my old friends from middle school and high school because i felt like i didn’t connect with them anymore. and where i work i’m secluded and by myself. i need help on making new friends, i’m an introvert and very shy so all this is very new and stressful to me.. idk what to do 😐
