Am I becoming addicted to my friends?

So...I'll try to explain it as clear as possible.

In this last year I've been strongly bonding with a group of friends of my university. Yeah, of course we've been knowing each other since university started, but we never really had the chance to grow as a whole group due to covid and lockdowns.

I've lost the count of how many experiences, parties and activities we've done throughout late 2021/early 2022, and we recently got back home after our vacation trip.

...I can't stop thinking about them. Like, seriously, I constantly think of how much I love them and how much they mean to me, how I wanna see them more and more as time passes by, how I can't litterally wait to meet them again. I think I'm starting to become addicted to this and it's starting to interfere with my focus and studies.

I'm also afraid of the future when I think about my friendships. In less than two months I'll move to another city (it's not that distant but still), and I'm terrified at the thought of losing touch with them, especially after this incredible connection that we've managed to form altogether.

What's happening to me? Am I seriously becoming addicted or it's just "normal"?
