Is it normal to be becoming distant with friends and starting to be alone?

First lemme tell you the story. I have this small group of friends. Then as time goes by, I feel that I'm not given the same actions as what Im doing. After our science class they're not waiting for me anymore as they go to the cafeteria unlike before. Then suddenly they are starting to create more friends and I am here like a clove of orange trying to fit in in the cloves of a garlic. When I ask them on the messenger they are just "seen"ing my messages. They're not that famous at all. Then I get tired. And decided to be distant, more serious, and giving them cold expressions like I'm the type now that is really hard to talk with. They're asking why aive changed and i kinda like woah ur the first one here
