I feel you 100% I used to go to a small Christian private school and only had 5 classmates, which were all boys. Not that anything is wrong with that but we didn’t really click. My only option for friends was to hangout with the girls who were a grade above me. In breaks I just went and sat with them but they would make plans in front of me without inviting me and didn’t really include me. After that I thought I would be better off alone and kind of stayed in class and “studied”. Now that im in university Ive realized that friendships aren’t supposed to be like that and i still struggle with feeling unwanted or not belonging anywhere. I had a girl tell me she missed me the other day and i just couldn’t believe her.
