Making friends in college from no friends in high school

as a senior in hs, Ive realized ive wasted my high school years with barely any friends by soley focusing on school. i have no one to text, no ine to invite for my graduation, Halloween, anything u name it. ive had acquaintances, but never anyone who are FRIENDS— who has a similar personality as me and we click, or people i can genuinely feel connected to and can actually consider eachother as number ones. im an extroverted person—ive just always had p bad social anxiety and self doubt plus a lot of “trauma” of people leaving. i want to find people like me and i want relationships in my life. in college, does it really get better and you find your people? has anyone went from no friends in high school to finding people like you in college? am i doomed for life? i want things to get better. spending my 4th halloween alone again
