Lack of self-confidence..?

i truly lack confidence!!i mean since ever!!!i have an image problem and am totally and absolutely self-conscious when i walk,talk or even laugh! i try looking into people's eyes to figure out how they see me,i know its damn sad & its not a way to live and am sick and tired!am changing am not gonna be the same anymore..its a very easy decision to make but its gonna be damn hard to follow i have to lose weight first to gain my confidence back,i have to make up with my ex *he had a lot to do with it* and i have to get my life back on track without counting on any1...D ur my bestfrnd and i love you but u have ur life together now and soon we will be out of each other's lives so i have to get mine straightened up before its too late...am gonna try to keep a daily journal of how my new me journey is working out!
