I don't know if it's OCD or paranoia, but e.g. I am of short stature, and if I read or listen words like "shot", "shoot" etc. I get really triggered by that to double check it so I don't really miss that it's not about "hating on short people". This also is true when it comes down to words like "tell", "tale", etc. because they are similar to "tall". 

Or "pool", "poll", etc. because I am Polish

This even goes further and if I read full sentences I am double, triple and sometimes up to 30 times checking if I really didn't miss a word. I am always afraid that if I got a sentence like

This is cool

I will be missing something which is "far on the right", like

This is cool                                                                              !

I think you can kind of imagine how life is to me, that I can spend up to 10 minutes on reading the same sentence over and over again. I am just afraid that a sentence is about insulting me in some kind of way, either because i'm short, or Polish, or whatever. If I don't check it it feels like I am out of control

And the worst thing is that even if I checked it once it's "not enough" because "maybe I've read it too quickly and it is insulting me somehow" etc. So I go back and double and triple check it again and again and again and again

The same goes as said for listening, constantly hitting the left arrow key when watching YouTube and even having subtitles on doesn't really help

Could anyone objectively analyse my problem and tell me what to do? I was once offered to take Prozac but I'd been suffering a severe case of DP/DR and Prozac apparently could worsen this situation, so I didn't take it.
