The same thing with my mom. She smoked all her life, never excersied and ate fried stuff all the time. But the only good thing that she did for me is made me play sports. I always ate well and healthy because I grew up in Eastern Europe where fruit and vegetable is natural without any chemicals. But my mom ended up with cancer, fat and unhealthy. As I said earlier, just do what's right for you and put an effort into yourself. When you love yourself and treat you right, then others will love you too.
