I give you a hand for your honesty, it would serve you best if you were to write down all the negative words and beliefs that you mentioned here about yourself in the complete positive way to re train your mind and your body so they become assets not a burden, Do continue to work out, do eat healthier even if you think you already do, you must develop yourself spiritually visit temples or churches read good stuff, find good positive role models and learn from them, there vocabulary, facial expressions, beliefs and posture. Do not be too attached what others think of you, best that you become the best you can be and continue on with a positive attitude and disposition, we all have our challenges to tackle so move on and do not give up. If you believe all the negative stuff that is what you will become.
Change happens first with you then the universe will support you but you need to take the first steps. Wish you well.
U need to blast this negativity outta your mind find somethin' you good at n' work on improvin' urself at it, set a goal and work hard to achieve it screw the ones who rejected u, who've been bullyin' u, who've been hatin' u.. use your energy for own good, even the bad energy that absorbs your mind and makes you feel worthless, use it to prove urself wrong, try that for once in your life n' you will never feel the way you do now again whenever you feel like killin' urself, put some music on and start exercisin' , go out for a walk, think about your goal make somethin' outta your life that'll get you on top o'this world, that it'll get you satisfaction and pride, never die hatin' urself! U're only 16, YOUR life is awaitin' you , don't end it without leavin' your print, and no matter how hard it gets or how bad it is, always tell urself, that u're goin' to MAKE IT!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
