Under 2 hours is honestly not that far. You can both very easily visit and spend a weekend together without the drive accounting for an entire day. My partner and I visit his parents about the same distance away pretty often. Also, it’s your education. Maybe she should’ve gone to a college closer to you?
As a sister too, go to the college far because I promise you’ll regret it for not taking the chance. Also as the days go by she will be okay and get used to you not being around all the time. College is a time to get more independent and start thinking for yourself and your future, sadly your sister won’t be there by your side every step of the way but that’s what life is like. You guys won’t be distancing from each other but being away makes seeing each other again so much worth it.
