Man I just wanna have fun. Help

I’m 20 and a junior in college, live right next to UCI but go to a different school and it just feels like I’m wasting my life away I have no friends and my life consists of sleep, school, studying, and work I wanna improve my social life and just have fun it feels like after covid everything just went to shit for me anyone get some recommendations. Recently started going to the gym and was thinking about getting into rock climbing / bouldering but that’s about it. Lmk if y’all got some suggestions for someone in their early 20 to improve their social life and just enjoy life.

Edit: wanted to say thank you to everyone who has responded and gave me ideas or just general advice I appreciate all of you and will possibly update in the future on how my life is going. I wish yall the best
