The crazy

Today, my friends had a bunch of "old group moments", which means they were remembering stuff from the beginning of last school year. Since i wasnt in their group, i wasnt included. What really annoys me about that is one of my best friends from elementary school is in that group, and whenever they come along, he shuns me. It kind of got better after i joined the group, but now he is doing it again. I feel horrible because of it, because it seems like he's telling me, I dont care about all the time we spent together, the laughs we had, the joy we shared. You could just leave and i wouldnt care. It hurts. Sometimes i want to just leave, but he's the only person who i can rely on to be there, maybe not for me, but just there. Do any of you killjoys know what i should do, because im lost, and ever so lonely.
