Privilege and Marginalization: Intersectionality

I am an able bodied white woman. I come from a two-parent household. I had a sister. We grew up in the suburbs. I'm pretty, well educated, spoiled, privileged in every sense. I'm also a troubled individual. I stumbled my way through my teen years, in and out of doctors' offices and hospitals. I dropped out of high school twice. I've been diagnosed with clinical depression, ADHD, generalized anxiety disorder, substance abuse and dependence, EDNOS. I've been labeled a slut, stupid, a whore, fat, ugly, a junkie, a drunk, a bitch, a waste of space. I've never really been able to determine how I can be so privileged and so outcast simultaneously. There are many inner struggles, but the all encompassing one is just that: where do I fall in society? I am a woman which marginalizes me to an extent. I am mentally unstable at times - stigmatized. I dropped in and out of school, leaving me behind my peers - uneducated marginalization. I have a criminal record - marginalized. I think I feel guilty for the troubles I've had in my life. I wasn't supposed to struggle; I'm a thin, pretty, heterosexual white girl from the 'burbs, boo-freaking-hoo. This is my biggest insecurity. I should be, and I very much am, grateful for the privilege I was born with and born into. So why do I feel like a freak?
