What am I?

I would say that i'm a short story as i'm a plain Jane. I'm not a complicated person with my own personality. Sometimes i just cant figure out something hidden inside me because i tend to keep my feelings and hold them until i could burst them out, at night. Being who i am now, from what i had experienced in the past before. My days passed by regrets, blissful and those mixed feelings and they are making me a grateful person who still have chances to an improvement and betterness in my life. I lose faith and give up on people easily so I don't lean on them to make my day, working in my own way so nobody would ruin me up. I'm not a pretender, which people would know when i'm mad, pissed off or bloomy. The struggle of being me is when i can't convince people well, i'm not trusted, reassured and being underestimated sometimes . They said that would be an encouragement for me to prove them wrong, but it's not that easy. It's such a bleak. Words drag me down easily. How worst my day would be, i would just end up crying my balls out.
