Im also dealing with this. I learned I need to accept my self the way I am and start to love myself first. Im reading this book on self-esteem and there is a example of how to do that. I stand in front of the mirror, naked, look myself in the eyes and just say that I accapte myself fully and unconditionally. I even started to practice yoga and meditation. I just sit on the floor close my eyes and breath slowly and deeply and reapet to myself that I love myself...of course I just started to do that.
