Sorry if you see this multiple times, I'm posting this on several subreddits so I'll have more people that might understand me. 

Also, I'm just writing as I think so I apologise if this is not sequential. 

On Sunday I was drawing in my room when I noticed a small bug (a silverfish, specifically) crawling across my bed. This immediately sent me into panic mode, so I instantly tried to grab and kill it. The problem is, I missed and it crawled under my bed never to be seen again. I'm in high school so I still live with my parents, and I ran downstairs to go tell my mom what just happened. She tried to comfort me by telling me it was "just a bug," but it didn't feel like that to me. That night, I slept downstairs on my couch thinking about all the terrible things that would happen if I had slept in my bed. This frightened me, so I let it rest and fell asleep. The next day, I decided to clean very specific spots in my house. For years my mom had scolded me for not noticing how dirty things could get, but now I suddenly was. I cleaned our entire silverware drawer, our bathrooms, I vacuumed the whole house, I changed my sheets, and I dusted my room. I was disgusted by everything I saw, and after hours of work, I finally decided that I had done enough.

But clearly, I hadn't. 

After I finished cleaning, I took a shower to get all the grime off. However, while washing myself I noticed that I had lost 20-30 strands of hair that just kept falling out every time I scrubbed through. I felt the hair on my hands I was disgusted by the itchiness it brought all over me. I decided that I would tell my mom about it because I was worried that I was becoming too stressed on minor issues just about cleaning. She told me that I was, "Probably just getting too worked up," and that I could talk to my therapist if I wanted to. This made me feel a little better because I knew there was someone for me that could help me get through my stress, but I still felt no relief physically. 

All of my stress is psychological--everything about it is. I know because all I do is think about a hair or a piece of dust near me and suddenly I feel itches all over. The biggest problem for me with this is that I feel like I can no longer be in the same room as my dog without feeling like ripping my skin apart. I love my dog so much but whenever I get near her I just see all the fur she is shedding on my clean bed, and I can't help but feel so angry that my room is no longer "clean." As I write this, my knee, ears, scalp, arms, *EVERYTHING*, is itching me. I can't go anywhere without thinking about the germs getting all over me... it makes me sick. I genuinely don't know how I'm going to be able to get over this. On one hand, I'm now aware of the filth in my house, and I'm working to get rid of it (this pleases my mom.) On the other, I'm losing enjoyment in life, losing sleep, and losing time with my pet because I can't get over this irrational "fear." 

If you have been through an experience like this, please let me know what you did to get over this feeling. I'm probably going to see my therapist soon, but having others' opinions is very valuable as well.
