My mom screwed up the washing and drying machine for me. She opened the garage door while both machines were open. Now, I am worried that a bug flew from the garage and went in both or one of the machines. I don’t want to use the machines anymore. What Do I do?

I live in my parents’ house and they are currently redoing the roof and the insulation in the attic. My parents’ house is at least 50 years old. The only way into the attic is through my room. I knew I would have to relocate but now I feel like my room is contaminated and can just never been clean. I feel like everything needs to be thrown away that was exposed to the old insulation or touched by the workers. No matter what I do I just will always think that my room is dirty. Does anyone know how to push past getting stuck with these thoughts? Or dealing with people making you feel worse because they don’t understand?

Earlier I posted about trying to get back to sitting on my sofa without a blanket covering it. And I did it, but now my day has been ruined. I left for two seconds and my cat decided to sit there, so now it's not clean anymore. This is because sometimes she's had number two stuck to her and no longer trust that she's clean. It took so much for me to just do that and sit without a blanket and now I'm just so done. I'm also scared to walk anywhere in my house. We sometimes get slugs in our conservatory and I don't walk in there anymore because there can be slug slime trails (it's carpet). The thing is, my mum regularly goes in there, my dad too. And then they proceed to walk around the rest of the house without changing shoes or anything. I'm just panicking because I was having a good day and now I feel like I'm isolated to my bedroom.

My sister is going to a concert and coming back to the house where me and my family live. In my mind her clothes are extremely dirty. And I know her coming back is going to cause a lot of strong contamination thoughts to enter my head. I’m exhausted already from pushing myself and I can’t seem to focus on anything when these thoughts are really strong. I’m in college and this makes focusing on homework difficult. I failed an exam the other day bc I couldn’t stop thinking about what I need to clean and then cleaning. It’s really exhausting.
