Brain fog is ruining my work life

I get brain fog super easily when stressed. Unfortunately I work in a very stressful environment with a lot of social interactions and my brain fog is making it hell sometimes. I call up a patient to the exam room, close the door, my coworker asks me what the patient's name is. It's gone. I can't remember. She smiles at me but I can tell it's the kind of "what the fuck is wrong with you" smile, asks me how I can forget when I just called her. I say sorry. She shakes her head in disbelief.

Sometimes I even forget where things are even though I always know where they are. Sudden questions throw me off so badly that I can only stare and have to genuinely compose myself to think, which takes too long and makes people go "ugh whatever" and go ask someone else or repeat themselves in a more brash tone.

My mind often drifts off into daydreams or thoughts, so I get caught off guard pretty badly when suddenly approached. I'm officially diagnosed with OCD and Depression if it matters and makes advice easier.
