Hobbies to try

Hello everyone I'm a senior in college and I'm in nursing school so obviously it rakes a huge chunk of my time and I only have friends from nursing school since we hang out so often doing clinicals and studying. When I do have chunks of free time on the weekend idk what to do with myself because I don't really have any other friends or hobbies. Since nursing school is nearing the end I want to be involved in more hobbies preferably ones that will help me make friends outside of nursing school and are cost effective for a college student. Things I don't have to do continuously but just something in my free time.things that will help me develop as a person you know what I mean? And are not too difficult lol.
