What do guys (younger side) do for fun?

For a little context im 19 years old and have moved to the city to start university, I have a large group of friends but they are also busy with studies so I don't get to ha gout with them much. I a quite socially anxious guy so I mostly stay inside by myself playing videogames or doom scrolling. Only other thing I do is go outside to do photography as I have an interest in cameras and am studying to eventually become a cameraman.

I want to find things to do that are enjoyable to do by myself as I don't want to rely on other people as I want to live in my world a little haha. I wouldn't say I am a very active person I can be quite lazy unless I really want to do something so I need some suggestions on interesting activities I can try get into.

Anything is appreciated just want to better my mental health and keep my sane and entertained :)
