Yeah, it will be strange. I moved to a new school 3 years ago and have made many new friends, before that I had moved from a school where I had friends for 8 years. I'm not going to lie, at first the transitions was hard and I had a tough time dealing with the new environment but I quickly made new friends and things were better. I still keep in touch with old friends too through social media which is great.
It's tough at first, but then you get used to it and it turns out to be a better experience than anything before. It's very interesting.
