I have no clue if I have friends. There are four of us in the friend group and we love being spontaneous and always text about everything. We are all really close friends for over 3 years, but there were many instances that made me question our friendship. Why do I stay "friends" that don't even consider me as a friend? Why do I want to stay with them even when they leave me out? They are the same people who throw birthday parties and not invite me, while our other friends are there. So one of the four people in my friend group threw a birthday party and invited the others in the group and other people, but me. I am not sure if I should be mad or sad about this? The whole group (the three of them) did not even mention the party and I found out about it by posts. They are the same people who took out our friend to Disneyland for their birthday and forgot about mine that was the next week. They all text and talk the same as they have always, like friends should, but I am just feeling a bit conflicted. What should I do? Am I just overreacting? I don't want to be alone, but I already feel alone. What do you think?
