i always have to have chewing gum with me as well, i pace a lot when im anxious about being s*, and live at home so whenever i feel anxious about v*, i always get in bed with my mum, as shes the only one who can calm me down! i like to do criss cross puzzles as well, as takes my mind off it, and also don't eat a lot for fear of something not agreeing with me. so glad im not the only one with weird habits!
