Do you hide?

I feel like for most of my life I have tried to hide within myself.  It started around puberty when I began putting on weight and felt like my family members looked down on me for my appearance.  I was lectured on my health and looks and started at an early age with a declaration of not caring what others thought, but it was a lie.  It cut me to the quick that people could think less of me due to my appearance.  Of course this idea only got worse as I entered High school and the world of media.  When my sister would come home with flowers and boyfriends and my chunky self had only the attention of boys who for good reason did not have girlfriends.  It was my junior year in High school that I began dressing in layers.  It was not uncommon for me to wear two shirts and a jacket, hopping that somehow I was hiding the belly or large breasts I was carrying around. I felt safer the more I had on, because then there was more of an excuse:  The heftiness was the clothes. No one could see the awful curves I was hiding.  I felt more protected like the more layers I wore, the less people would see of me.  This mental hiding only progressed from there.   I began hiding my dark depressed thoughts deep within myself, writing obscure vignettes and poems to express the me within that I didn’t know how to process.  I put on a smile and executed all the things that were expected of me.  In doing this though, I felt like no one knew who I really was, and in truth I felt like I didn’t even know myself.  I went from being social and outgoing, to more of a homebody as I felt more in control over how I could present myself and how in my opinion, raised the odds of being accepted. I am assuming I am not the only person to do this.  Why is it when we are not feeling well about ourselves (bloating, sick, etc) we opt for the large bulky sweatshirts and pants big enough to fit two of us?  Yes, they are comfortable, but more important; they allow us a little bit of anonymity.  I know there are other ways to hide and have addressed ways I revert to when I am down.  How do you hide?
