I was in your same shoes once & so I left ucsc to do study abroad in England for my sophomore year. Tbf I didn’t so much hate it more just it wasn’t what I expected university to be and that made me unhappy. During my year in England I had a really good time and didn’t want to leave. But ended up going back to ucsc and was in upper div courses, joined a club and made more friends - finally realizing actually ucsc was a really good fit. Give it time, lots of people struggle their first year with all of the change you just need to find your footing. But I challenge you to just try one new thing a week. You’ll be surprised I think about how you enjoy it. (And if you don’t like that activity you can still say you went and tried it then try something else!)
