I felt that way in the beginning of college. When I revisited my high school I would notice the smallest change and it would really throw me out of the loop because I wasn’t there when it happened. It’s almost as though nothing changed or they never noticed that I was gone.

Your sense of noticing these things is good, because it shows that high school was an amazing time for you. I’m sure those who did not receive such a fulfilling 4 years would not feel the same. This sense of attachment makes us realise what we want and what we enjoy, and that is not wrong. Except when changes come in (which is an inevitable thing), it can be a little scary. But it’s all worth it.

However, over time, I became disconnected towards the changes that were made to my school. After 5 or so years, there were so many changes that I could not keep track of what was the same and what was different. I took that as a sign of settling down into the life that I have now. And I am sure that you will too, and with that, have a place in your heart for what used to be familiar to you. =)
