All's Lost I Cannot Be Found Again

My life has always been F**ked up..Problems after problems i faced and facing has made me realise whether I have a purpose in Life in the first place. Even all the good I've done in my life has not given me a break, a chance a glimse of happiness. a friend asked me for a moment in my life that i was happy...There's none....cos, every happy moment i so called had will lead to disastarous measures. All bad things are happening to me.......What do I have to Live for...? I dun even know now. I've got a relationship that goes nowhere, I lost my job for something I did and let down good friends at work...something that i cannot salvage. Those who find out what happened and if it effects you...i am sorry.....Ive doe so many wrong things in my life and this is the only wrong doing that i feel with regret that i did it. I am sorry for letting everyone down. It is hurting me real bad and it should be hurting even worst for what I've done.
