Why don't mothers support each other?

I was disappointed and suprised to read the responses on feeding on another question posted in here recently. I shared my personal situation with the asker about how i was unable to feed completely to my own detriment. No one knew the ins and outs of my plight and yet, i had nothing but thumbs down from my fellow mothers cause i gave formula. Reading through the responses i realised all mothers who were supportive and unable to feed for whatever reason were given thumbs down. I feel quite angry and disappointed that people can be so judgemental about this topic. Everyone knows is best - obviously! but for some poor mothers IT ISNT AN OPTION... would you condemn a mother for giving formula to her newborn because she has her removed from cancer? I support feeding where possible, however i also support my fellow mothers in their own choices. Mothers have enough guilt to deal with from society as it is. Thanks for listening.
