I don't know about paranoia but to help you sleep try turning the lights down an hour before bed, drinking some chamomile tea and reading or writing a diary. It's best to do this while laid in bed, valerian root and st john's wort work too. If you think reducing your anxiety would help get bran flakes reinforced with iron, folic acid and vitamins. All these, but especially vitamin B8 are helpful, I typically eat this for breakfast with wholegrain toast and celery which is high in sodium and folic acid. The size of the meal also reduces anxiety, and you can eat bran flakes with yoghurt for a dessert as well. I also highly reccomend starting a daily supplement of inositol, or inositol and choline, I avoid choline myself because I worry about the fish smell.
