i hate my friends

I swear my friends hates me or smth they always leaves me out and whenever they take selfies they always leave me out like for once we were walking to another class n they suddenly had a convo and coz i didnt understand what they were saying i asked them n they ignored me completely. Other times when like in our gc they always hve convos w/o me or those only they 3 will understand n when i type like smth there they will js ignore it but if it was one of them they will reply. Im like always their backup choice
