I was not a joiner (and still am not) and yet the activities/volunteer stuff I “joined” early Freshman year at college really saved me. Not that I made lifelong friends, found my soulmates, etc. but until some actual friendships developed, having people who “saved me a seat” (sounds so quaint) or waited for me outside a lecture hall so we could walk over to a meeting together really cut through the isolation.
At my last college reunion, a guy who I met through some activity in September of Freshman year (and quite literally- have not seen, thought about, or interacted with in 40 years) told me how much my “friendship” had meant to him back then. He was from a small town, rural place and felt hopelessly out of his league at college. I was in a dorm with a lot of prep school kids and felt like they spoke a different language then I did coming from a huge suburban HS. We ate dinner together 5 times? Walked each other out of the library 10 times? and that was really the extent of our friendship. But we were both in tears as he talked about how awkward Freshman year was.
These early connections can really make a difference. I LOVED college and can barely remember how miserable the first few weeks were… but when I do force myself to recall how tough the transition was I end up grateful to all the other “out of step” Freshman who were so kind to me.
JOIN something, anything.
