Should I say something?

I had an interview last week. I didn’t perform my best even though I prepared because of my invisible disability. I thought I’d do fine because it was on video.

Being exposed to certain chemicals causes brain fog and triggers my migraines. I’m away from home so should have taken extra precautions. I went to use the washroom 5 minutes before the interview and got exposed to the chemicals. I had a hard time focusing, reading my notes, and wasn’t as well spoken as I would normally be in that situation. I ended up needing to take my migraine medication afterwards.

I don’t want to say something because it feels like I’m making excuses, but I want to say something because I’m embarrassed by my performance, and I know this job is what I’m meant to do. I’m not applying for any other work but this kind, and it’s in a Ministry that aligns with my interests (which I forgot to mention even though it’s highlighted in my notes).

Should I say something or let it go?
