I feel your pain. I'm 26 and have felt kind of alienated and lonely since I've changed my diet and way of life. You know, it's hard, but it sure is worth it. Just think, you're learning so much and the people around you will more than likely need your help someday. Some of the same people that gave me the most trouble are already asking me for advice occasionally. It sure is nice to be able to give them some sound advice.
