Wish there was a way to tell people it physically hurts me when someone turns lights on in my vicinity without sounding like a little bitch baby

i had a coworker who did it every single day at my last job but I didn’t say anything bc im a little baby bitch and i got the feeling shethought my light sensitivity was stupid bc she’s not very nicetoday my boss turned on like 6 big fluorescent lights to light ip the space where im workingand i just waited until she left and then turned them back off fudssg
