am i even aloud to be sad?

so what?

helpli, my name is leeuh, and i am 17 years old. I know, im young and still in high school, never expeirneced the true "horrors " of life, but part of me feels like i have been dragged through the dirt. How can I, someone who isnt bullied, isn't homeless or starving, im passing all my classes and have friends, claim to be sad.I mean hell I've got it going, my mom loves me and so does my step dad, so shit, why do i feel stuck, like I cant be happy. I look around and see other people who are going through a shit ton more and I just feel worse about feeling bad. I feel like i dont have a good enough reason to support me being sad, hell I dont even wanna call myself depressed because i literally have no reason. Again my life is almost literally perfect. But why am i feeling this way, how do i fix it honestly
