Answer: Anxiety is fear, usually unjustified so first find out why you are so afraid of. Remember that no one is going to eat you. I don't say that to be mean. It could be that supplementing with amino acids like Tryptophan, or Tyrosine, or arganine can help. Often Depression and insomnia are symptoms of an imbalance occurring in the regulatory glands [Hypothalamus,Pituitary, or Adrenal] in your brain and supplementing with amino acids can help. [It has changed my life] Amino acids are simply the compound make up of proteins. Try any Health food store for an array of options. I take Amino Sculpt, when I can't get that Natural Source Amino Night and a soy protein powder. Also Google Hypothalamus gland and watch the DVD What The Bleep do We Know. I know this doesn't exactly answer your question but I hope it helps to offer some options
