Contamination ocd

Hello everyone, I'm new here and have severe contamination ocd that has been happening the past four years since I was 20. I'm 24 now and it seems to be getting worse. I don't want to be around kids because I know they're germy little gremlins and carry the main thing I fear that caused my ocd to worsen. I shower whenever anything above my chest has been touched (neck, face, hair). I wash my clothes after one wear because they feel contaminated after the use. I refuse to let people touch my bed or clean clothes. If I hear that anyone in my family is sick I freak out intensely and have to stay away from them. I also shower if I've been in public and people were coughing near me. If I don't feel like showering and that my above triggers aren't contaminated I just wash my arms up to the elbow and go to sleep because I sleep in short sleeve shirts and my arms touch everything all day. I refuse to touch my face, neck or hair after touching my phone or anything else. I bring a travel blanket with me but have to wash it after every use. I use my shoe to open doors and press the cross walk button. If I can't use my shoe I use my pinkie and immediately handsanitize sometimes twice just to have my hands feel clean. I have to use a utensil to eat when in a restaurant and would ask to change it if I see it touch anything. I work at a place that requires me to use a phone so I have to shower and wash my ear. I hold my breath when walking past people. I can't sit back in the car or on the couch because it'll contaminate my neck and hair. I also have to do a double wash with my hands to feel clean. I used to do it for 20 seconds but I do the hand wash for 20 the 1st time then 30 for the second. I can't wear purses with straps that touch my shoulders, same with back packs. And I use so much soap and lotion that don't help keep my hands moisturized. And if I get triggered by anything I sit there in a quiet rage and ramble in my head because I know saying anything out loud will have me look crazy. There are times though that I get angry and close to tears when it feels like I've been contaminated and when my family makes fun of me for things I feel I have no control over especially the intrusive thoughts, emotions, anger, fear, and tiredness I feel on a daily basis. I'm scared of doing exposure therapy because I know they'll have me touch something contaminated and have me touch my face and not wash it how does that help it'll just make me angry.
