Stella Trim Heartbreak can drive a person to unhealthy habits, but it doesn't have to. Take your anger and heartbreak and allow it to be the motivation you need to look good and feel great. After a while, the exercise and weight loss won't be about your ex, but it will be about you and how you feel. Proper nutrition and exercise can replace those self-doubts and help you realize the great person you are. In the end, you will see that you want to be healthy for yourself, and not anyone else, and making your ex jealous will just be an added perk.
