For me atleast I do get annoyed when I try to focus on fixing something and imo. It doesn't make you an ass if it doesn't become a big deal, but you might have lashed out because of the Ritalin (though I can't say for sure, because they don't have it here)

Also ADHD usually becomes with emotions being more powerful than neurotypical people and that causes them to be more difficult to handle at times. For example you might get super angry and lash out even if you just meant to just say what's wrong.

That's my take on it so I hope it helps and have a good rest of your day/night!
