Gone vegan but have no support?

I am so amazed at how immaturely people can react to this. My advice to you is to visit credible sites (american cancer society, mayo clinic) and look up veganis. You will see that they advocate a plant based diet to avoid certain illnesses. Then visit peta.org , goveg.com, etc... to find recipes and health tips. Try to visit a nutritionist if possible to plan a balanced vegan diet. Once they see that you can eat well and stay healthy I would hope that the attitude stops. I am sorry that they are being like this. A lot of people put a bad stereotype on veganism and treat you like an outcast. prove them wrong and stick with your own decisions. peta.org has a great discussion forum where you can ask questions and get support, just make sure that you take it all with a grain of salt and do your own research.
