after shower. itchy skin leads to anxiety and panic. usually fear of contact of sight of dirt and food crumbs and stains. after a shower hot or cold my skin gets a itchy/prickly feeling. after drying off it gets worse for about 20 minutes to an hour. while itchy i feel like i have anxiety. when i feel or see anything dirty i just start panicking sometimes unwilling to move. it happens more with food and crumbs(definitely unrecognizable things and pieces of food that may have feel on the floor a while ago). . i regularly avoid direct contact with old food/bits of food but i can easily just overlook them.
