I am lonely and I don't know how to find friends

Today I am 25, I have not gone out during my entire college years, I missed the best years of my life. My college ended a year ago and I have been on home quarantine for 3 years. I have no friends, I feel so alone. I don't know how to find friends, I want friendships but I don't know where to start, I want to be around people, I am tired of being alone, how can I find friends ?
