I'm really not sure if I have some sort of disorder or if this is just a normal obsessiveness type thing, but I absolutely can not relax unless my apartment is super tidy and clean and every single thing is in it's place. Even my storage cupboards have to be extremely neat and for example if I stack books, I'll stack them in size order and spend ages finding a position for them that takes up the least amount of room possible.
I'll chuck away literally anything that bothers me and once I decide I don't want something it has to go immediately. E.g. I had a new mattress come, my OH said that he would take my old one to the dump for me later that evening, but having the old one take up room and look messy was annoying me so much that I cut it up into small pieces with a bread knife and put it in the communal bins in my apartment block doing about 5 trips 
If I'm at work I'll sit at my desk and feel stressed that I have my sister's stuff at my place (while she moves into a new place) and it's taking up room and I visualise chucking all her things away!
Writing it down it feels really clear-cut that I do have OCD but in real life it doesn't feel as bad as it sounds. I also have really bad anxiety so I'm not sure if it could be linked to that? I feel like I absolutely can't be happy until I have nothing but the absolute bare minimum. Is anyone else like this?
