I hate this feeling

I hate feeling contaminated, food makes me feel contaminated not necessarily that the food is poisoned but just the feeling of eating food and having food in my stomach feels so terrible and gross like my whole body is dirty Also breathing and air makes me feel Contaminated but you have to breath. But it's feels so bad. Also my shirt sleeves have wholes in them from using them instead of using my Hands so now they also feel contaminated and like they aren't working properly. Also it's allergy season so everyone is coughing And that is super triggering
