You’ve felt secluded from your best group of friends due to your busy schedule. You get upset seeing them hang out and have fun without you so maybe this week you should make time to see them. Let them know that you have felt left out and your feelings have been hurt; they probably didn’t even realize they were hurting you. Honesty is the most important thing in friendships so make sure you are always honest with them. They will surely make an effort to try to always include you from now on.
