Oversensitive

idk, i just feel kinda left out by my friends. we have this subject where we have to work in groups, and when i checked the list, two of my friends were in one group and the other two were in another, so all four of them got to be with someone from our circle except me. none of them even asked me to join their group or anything. idk, maybe i'm just being oversensitive or smth, but it kinda hurts knowing that i'm the only one who ended up without any of my friends.
