Contamination

all morning i have been feeling like there is dirt and grime on my skin. i showered last night. i washed my hair on tuesday night and i will wash it tonight. but i feel like there is dirt in my scalp and in my hair and i feel like i haven’t showered in weeks. i don’t want to feel like this anymore. every day i am anxious about how clean i am and its taking over my life. any tips?

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?

This is a long one lol but basically, a couple of weeks ago I went to the toilet (#2, sorry for the tmi). Let's just say it was messy. I remember that a speck of.. #2.. Fell off the piece of toilet paper. This was probably the worst thing that could ever happen. I can't remember clearly but I'm pretty sure my jeans were on the floor underneath near where the speck could have fallen. There was also a towel. I don't know exactly where it fell as it was so small, but I made sure both the towel and the jeans went in the laundry basket and I cleaned the floor near there. Fast forward to like the next day. My mum does most of the laundry, so she will have picked up all the towels and clothes from the laundry basket and taken them to the wash. The problem is the speck. I don't know where it went but if it was on the towel and she picked it up.... Thus, contaminated mum. And she also puts clothes away that are dry. I remember that day she put my hoodie in my wardrobe, and I haven't worn it since because I feel it is contaminated. I haven't worn the clothes that have touched the hoodie. This leaves me with not a lot of clothes. And today I finally snapped and picked up a sweatshirt that had maybe touched the hoodie. And now I'm just sat here spiralling, wearing it. What if it touched the speck? What if the speck touched my mum and then touched the hoodie which then touched the sweatshirt I'm wearing? Please I'm so scared.
