My daughter is my height but has your build. She tells me that I need to be happy with her even though she is not tall and thin. I work hard to keep my weight down, and I have been successful without starving myself.
I have learned from my daughter to be happy with an outward appearance that is not the ideal. It is what is inside that counts. She spends her days helping others. I recommend that you help others and be proud of who you are.
