I'm 18 years old in the last class of high school.I feel depressed because some of my classmates and from other classes behave awful to me,and they make fan too.They are esepcially boys.I don't really know the reason cause I have never done something to hurt them but they hurt me.They used to call me ugly to my ex bf but I am really not.I am jealous when I see them enjoying talking and behaving so well to the other girls :'( I feel unloved and lonely in my school.What should I do?
