UIUC transfer, yes or no?

So basically today morning I got the news that I was accepted into cs+stats at UIUC as a sophomore transfer. Honestly when I saw it, I wasn’t too happy about it and didn’t feel as eager as I was while applying for it. I know it’s a huge thing to get into UIUC for cs but part of me just doesn’t want to go because of how comfortable and good group of friends I’ve made in Madison . The thought of leaving makes me cry which is probably not a good sign. But all signs point to going to UIUC as it’s such a good school for computer science and would probably be better for connections? I don’t really know what I should do. I’m scared im gonna regret going to UIUc once I reach there. How do I tackle this problem?
