I relate to this, a lot. I was always a people pleaser, never stood up for myself because I felt it was the only way to get people to like the fat me. It's taken a while but I have learned to be assertive, and not to undermine my own happiness by giving in to others. I am far from mean, but I am not the apologetic, submissive person who was always hiding her light and letting others shine. Counselling is a great option if the transition gets rocky. Best of luck!
