Had a similar issue in college where I wasn’t social enough to form connections in class. I found clubs and work were where I formed my friendships. Places where I was put in a group for extended periods of time. Also, learning that if you’re the one who wants to form the friendship you will most likely need to be the one who initiates conversation and activities for some time

If you’re interested in programming see if there are local beginner hack-a-thons where you can be in a group to complete a project with people that have a similar level of experience.
