I am feeling really down. My sister smokes and has drank in the past. She lies to my parents and to my sisters as well. When my parents found out she got into a lot of trouble, but they had trouble trusting her then. She continued to lie and we have found that she did not stop smoking. We haven' told our parents again. I'm so upset because my parents don' deserve this. I now always think of how much easier it would of been if she wasn't born. Please help. I've prayed but I'm filled with so much sadness. What did me and my parents do to deserve this? I can't stop crying.

thank you
