Dirty space? Anyone?

I can’t touch anything my parents touch. (If any part of them touches it) . That includes people. I’m so isolated from my family I hate it. I was forced to move out because the family dog accidentally got in my room. It’s been almost a year and all my stuff is still in my old room because everything the dog touched is “dirty” now. I feel my workplace is “dirty” now after I tried to do an exposure and go to work “dirty” but it backfired and I have too much anxiety when I’m there and I have to come home and wash everything I touched that I need to bring with me to work. But it’s really difficult because I have two jobs and I have to go from the “dirty” job to the clean one and it’s all too much. I want to quit the “dirty” one but i don’t know how and I don’t want ocd to win.

does anyone know how to deal with that feeling your clothes and things you own are dirty and washing/cleaning them doesn't help?

I feel so weird and dumb right now, but my brother just moved back into town and needed a place for his things. His “things” meaning a dresser and bed. Well turned out to be a lot more than two things. My anxiety started racing, I could feel my body tense up, I couldn’t catch my breath. Now everything he has brought from “outside” (from his old apartment/ from touching the inside of the dirty y-haul) to inside my clean room. Now I’m freaking out that everything is contaminated. They put it in the bedroom I don’t use, except to store my extra “things”. Now his things are touching my things that I have left in that room as storage. I don’t know how to get out of my head that his “things” are contaminating mine??? Now it makes me not want to use that room.
