Handwashing OCD

sorry this is super long i just wanna know if anyone else has been thru something similar bc i feel super alone 🩷 i have super bad contamination ocd. it was bad already but my house was like my safe space until a few months ago someone brought something into my house that i considered ‘contaminated’. and so then i felt like that part of the house was contaminated, then it spread to everything outside my room (since family is moving around touching stuff) and then somehow i got convinced everything in my room except my bed is contaminated and i need to wash my hands after touching it. in my mind its like the contamination just infinitely spreads to things after the tiniest bit of touch. idek what im afraid of anymore or even what the original thing was but i can’t let it go. when i have to wash off contamination i have to wash at least 4 times or until it feels right, or sometimes take rlly long showers and wipe down all my stuff. i even throw away food and clothes or just whole items sometimes because they feel so contaminated i don’t want them in my space. i can’t be super near people or have anyone touch me, and i also can’t bring anything new into my room since it had to go through the entry of my house which feels contaminated. i feel like all i do is lay in bed and then wash my hands and do compulsions so i can go eat or do other stuff around the house. also i never go out because i’m bc people outside make me feel dirty, and i hate thinking about how many people have touched stuff in stores or in public and stuff. so im just in my room worrying all day. i feel so trapped and the contamination/avoiding it is all i think about anymore i barely have time for anything else and im never present when i talk to people because im worrying about if i accidentally got contaminated. im starting erp next week and knowing that im going to have to expose myself to things is really freaking me out. does anyone else have this kind of ocd ? im exhaustedddd 🥲🥲💔

I haven't been able to read about experiences similar to mine when it comes to my perfectionism OCD so I was wondering if anyone had any "uncommon" experiences.

Does anyone have any tips that helped them? Mine is due to a specific person and I work with them so it’s been really difficult. I’ve started ERP which has been reaaalllllly challenging and I would love to hear from anyone else that has gone through any type of contamination ocd and how they have overcome or are fighting their way through it. Thank you!l
