Help I’m freaking out!! I saw dog poo around me on the street and I thought that I probably stepped on it but nothing actually stuck to my shoes so I went into my house as usual , and then thought maybe there was a trace of bacteria and it’s all round my carpet should I be worried

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.

I’m so scared. Part of me feels ok and part of me feels like I need to clean everything off. Basically my sweater had a stain on it from food it was newly washed but I decided to throw it in the wash again. While throwing it in the laundry basket I noticed a specific type of clothing that scares me. I quickly put the sweater on top of the used laundry and left. My phone was in the living room and I’m pretty constantly scared it will get contaminated by laundry I’m not sure why but that fear started randomly. Anyway I had to walk past the living room to wash my hands in the kitchen because someone had to use the bathroom badly and was waiting for me to just throw my laundry in to go to the bathroom. Anyway I’m scared I went near my phone or contaminated it with my hands. I can’t remember the details fully either but I just remember walking straight to the kitchen but I don’t know. I’m really scared and I want to clean everything like my phone and everything it was near. The thing is my fear is real because used laundry is so gross. What do I do? When throwing clean laundry in a basket should you wash your hands? Do most people? Even if the article of clothing isn’t dirty? Because maybe my hands accidentally went near the actual gross laundry I don’t know

I went to the pool and laid on a lounge chair that had bird poop on it, and I got bird poop on my leg and brushed it off my leg because it was dry and like crumbs I didn’t think of it at the time until I was on my phone then I realized a few moments later about the bird flu and I have a cat do I now have to shower and wash my hair and clean my phone or is that just me worsening my OCD should I leave it alone or should I do those things because I just wanna keep my cat safe
