I am extremely scared that some words can have a bad outcome. Then sometimes my mind wonders and thinks about those words. And then it looks like i accidantly say them. Afterwards i need to check. Did i really had the intention to mean what i say? What did i thought while saying it. Then i try to form an intention in my head (which is ofcourse not really my intention) and then i say the word in my head as so to reproduce the scenario to check wheter i said something wrong with an intention. While doing this it looks i utter the words but because i now have like a intention in my head i sometimes come across situations that it feels like i say the word through breathing.

Sorry for overcomplexing things... but how to deal with this.
I myself also have adhd and am also very negative and highly critical. Very scared to make mistakes.
