Not really. If they were worth it to you, or you were worth it to them, one (or both) of you would work hard to maintain the friendship. Some friends are forever. Others come and go. People change. And when you're in high school, and even college, your world is so small. You're confined to being friends with the people you share a classroom with. People you might not even be that compatible with. When you go out in to the big bad world, you can be anyone you want to be and you can be friends with anyone you want to. I love that tbh.
Don't dwell on the past. Think of the amazing new friends you're going to make in the future instead.
