Need help making friends

So I’m 21, ganna be 22 in August. I have to be honest about something. I’ve never really had any friends in my whole adult life. I’m going to be a senior in college and i have yet to make any “life long friends”. My last best friend I had stopped being my friend in 5th grade, and ever since I’ve haven’t had any good quality, stuck around for a long time Friends. Any ideas on how to meet people? And make friends? Am I doing something wrong...?
