I am a recent vegetarian, as well as a lifetime determinist with an anxiety disorders, which typically manifests itself in obsessions with my health and my obligation to myself to maintain physical health without unnecessary detriment to my mental health and the lives of other animals and the environment. Since becoming a vegetarian, I find myself in a bind regarding the amount of stress that has been placed on me, in concern for my health, compared to the rather small impact my vegetarianism has on the environment. I CANNOT, in keeping with my principles, eat a terrestrial animal that suffers as I do. However, my reasons for not eating fish are mostly environmental. Since my stress would be mostly alleviated by the inclusion of fish oil in my diet, over say flax---which, like soy, messes up my estrogen levels, thereby exacerbating other psychological problems, and the alternative (flax instead of fish) has such a minimal effect on the fishing industry and the environment, is it ethically justifiable for me to take fish oil, though it seems to support the notion that we need to cause suffering and harm the environment to live healthy lives?
