Is it normal i can't say words/sentences that don't feel right?

I want to ask you something and I am serious-trust me. Are you interested in mathematics ? Actually, You are being too logical, which will sound funny and peculiar to most of the people. Though this quality of yours might be rare, but there is nothing 'abnormal' in this world. In fact, 'abnormal' is a label which majority of people keep in their mind to consider themselves as normal. 'Abnormality' might be an extreme end of a spectrum, it might be a deviation, but a person who has that thing knows that it doesn't follow a 'CHOICE', like homosexuality was once considered a paraphilia, but now it has technically been removed from the list, becuase it's a programmed thing (though unproductive and might cause permanent physical damage, that's why considered an anti-natural defect). Many of the geniuses didn't know how they got the answer of the grand unsolved question, which made them famous. Even in their own testimony: it just came to their mind. People affected by 'autism' syndrome turning genius is not only a matter of fictitious screen presentation. I suggest you to go through philosophy. It's a work of intellect like mathematics. Analytic, where you will truly find discourses and treatises and dissertations(in the form of articles) which would be considered as weird and bizarre(surreal) by most of the ordinary(practical/pragmatic/empirical) people.(I am telling you this from my practical experience, if you take my suggestion for granted, you will see there are 'peculiar' people like you in the world, the fact which might soothe you). I think you are suffering from abstraction , reification so to speak(considering something abstract as concrete). You might have hidden talents other than those of practical field(life), who knows ! I am not joking with you....I ask you to consult the internet(including Wikipedia) for which you don't have to go anywhere and you can get free access form home. I suggest you to learn philosophy, if properly learned, I can even cure Rape Trauma Syndrome partially. It might inspire you.

Its totally normal, similar things happen to me all the time, I think you have OCD. Not the clean orderly kind, the crazy kind that doesn't make any sense, thats what I have. Im not sure if its this way for you, but when something like that happens for me, my mind usually tells me that somethin bad will happen to me if I do the thing. For example, Im emetophobic so I have a hard time saying words that relate to vomit, even typing the word feels crappy.

What the fuck

I always think hanged should be hung. Hanged just sounds wrong

WHAT?
