What you said about hand-washing reminds me of my own OCD. If I touch something that is “contaminated,” then I feel like I have to wash my hands, sometimes more than once. Also I thought that what you said about unwanted thoughts sounds like it could be OCD too, like if you have to argue/react to them or something like that (I can also relate :/ ).
also some things you mentioned like wanting things to be done in a certain way and personifying objects are traits that autistic people tend to have but they do not necessarily mean that someone is autistic
(I would definitely recommend researching neurodivergence/OCD if you want)
