So, my mum thinks this is normal.

I think I have OCD about cleanliness. My room has to be 100% clean, I used disinfectant wipes to wipe my beside table and dresser. Everything has its own place, if it doesn't, then it won't stay in my room. I clean all my makeup products after I use them, and disinfect all my powders and cream containers too. If I feel like its not clean I won't sleep until I clean it even if it takes me hours. I wash my bedding on a weekly basis, and if someone stays over in my room (like my friend) then I change the bedding into old ones before they come and then change it again after they leave because this thing inside me feels like they're dirty. If anyone touches something inside my room without washing their hands before, I will disinfect that and anything its near. I was a inspired to write this when today I was getting ready to wash my bed sheets, but I didn't have a place to put my duvet, because I believed everything in my room was "dirty". I eventually put it on a shelf inside my wardrobe, but as soon as I did I realised it was touching my blue coat which had been used but not washed. This caused me to get very frustrated and upset and led me to cry, and eventually make the decision to wash that too.

My OCD seems to only be part of my bedroom. Recently I have stopped placing my schoolbag, and all other school items in my room because I think they're dirty, disinfecting that every night too.

About a year ago I also stopped touching my little brother. I have not hugged him in a very long time and refuse to share anything with him. I have developed this mentality that if he touches something than he has "infected" it and it has become "dirty". My room is completely out of bounds to him, and if he does enter it than I would disinfect and steam anything he has touched. I have stopped using the hand towel in the bathroom that we share because he wipes his hand on it and dry my hands in my hand towel I hang in my room. It seems to become worse and worse, so much that I don't even use the notepads and pens that he uses, nor do I ever touch any of his items or go into his own rooms.

Sometimes I think I need to go and see someone and get help but it has become very hard for me to talk to my mum about it. I mentioned this once to her last night, which she responded by saying that my behaviour is normal. Part of me thinks she refuses to believe that there may be something wrong with her child.

Advice and opinions, anyone?
