Ok, the other night when I was working, (I work nightshifts at a warehouse that's next to a bagel factory.) I appeared disoriented and confused to a lot of my coworkers. Everything felt "normal" in terms of my mental and emotional abilities, and the first part of the shift went fine. (I work 12 hours in a shift.) However, during the second part of the shift, I somehow felt more confused than usual, and I kept on asking questions to my coworkers, however, they were just questions to clarify something, such as "Do I put these boxes over here?" or "Should I take this wasted product to the compactor?".
Eventually one of my coworkers asked me if I was "high". I replied "No, are you joking?", and he said "No, I'm being serious, you seem really out of it tonight." A couple of times he got fed up with me and yelled at me and swore when telling me what to do, for example, "No, you put it in the f*****g freezer!" or "Unload the f*****g truck!".
I've worked with this person before for about a week, and every past workday has been fine, except the last time I worked.
Any advice on what to do?
(Also, this is sort of unrelated, but I have a "theory" on why I was so confused that night, I took a generic form of my anti-depressent medication instead of the "company regular" one. Would that have anything to do with it? I take Adderall 60mg for ADD and Effexxor 300mg for depression)
