Starting back again

What I'am really good in, is complaining. But I'm tired of being that kind of person. I want to be the kind of person that can do whatever she wants. I need to stop my dependence for food, I need to get a life. I lost 22 chilos in a year (from 102 to 80) but I started again with my bad habits. Now that is time to change, getting my perfect bmi (76 kl) and my personal goal (60 kl).
I'm doing this only for myself. Because I worth it.
