I can understand your frustration but look at this way. What you did by giving birth and breastfeeding is one of the most wonderful miracles there is. Your breasts are just doing what they should do after being worked so hard. You not only brought a life into this world but you nourished it for the first few weeks/months of it's life...you sustained it with your body, something you were created to do. Relax and eat right, exercise and enjoy your child. Meditate on this and you'll be happy with what you've accomplished.
