cant get into relationship

didnt ever think id come to reddit for this but here i am. i (15f) constantly compare myself to other girls. not because im like insanely insecure or anything but because they can get into a relationship so easily and im just there. its like no guy pays attention to me and ive tried to not let it affect me but its affecting me. ive been in 2 relationships which were in middle school. im in my second year of highschool now. anyways ya just ranting 😔
