What's wrong with me? I have this thing about feeling like everything is dirty and focusing on?

every little spot, like hair on my vanity after I comb my hair, or if somebody has a spot on their clothes, or wearing socks in the house but if they get just a little dust or hair on them they go in the clothes hamper, feel like I should always wash my slacks if I just wear them once and sit somewhere like a theatre or restaurant, notice even very faint smells in the house so I have to use Febreeze, I have somebody clean my house every 2 weeks and I clean in between but I just keep noticing dirt everywhere. What's this?This is just a short list, there are a lot more. Also I look at other people and wonder when they showered last or how clean their toilet is or if their underwear is fresh.
