I think my family tends to learn towards a bit of anxiety, so I can begin feeling a bit overly anxious about a number of things. Right now I'm terribly anxious about my new cat I adopted Saturday. She's been sick twice now and my mind jumps to liver or kidney failure. "Is she drinking too much water?" I don't know. :: shrugs :: It can drive you crazy, really. Have you spoken to a psychologist/counselor/therapist/psychiatrist about some of your obsessions?
I'm not too worried about gaining weight back when I hit goal, because this is an entire life overhaul for me. I'm never going back to eating processed packaged foods. I am really looking forward to getting more into the Traditional/Real Food Movement.
I look forward to growing my own foods, maybe even grinding my own grain and backing. I already make some ferments. There is a whole "real food" world to explore.
