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

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.

i’ve already posted about this before but i keep thinking about it. i was sitting next to a dog and it was laying on its back laying face away from me. i kept getting intrusive thoughts about touching the dog inappropriately. and i was petting the dog to prove to myself that i wouldn’t. i remember i was leaning on the dog. then he kicked me with his back legs three times. i also was rotating my shoulder cause it pops and cracks when i do and i was trying to relieve it. i think i touched the dog and on purpose too, because thoughts were going through my head. after the dog kicked me i sat there for a second just pure panic and i ran to the bathroom, just crying non stop. i dont think i deserve to cry tho. i think my life is a over. the more i try to remember the more scary thoughts of what could’ve happened pop up. i’m just in denial and i want to be sent to a mental hospital.

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.
