Boss doesn’t believe I have covid

Y’all I tested positive last night for covid. I called my boss right away to tell her and she said she needed proof so I sent over the lateral flows. And she said she needed proof they were mine so I took an actual video taking the test and showing the results from start to finish, she then demanded a pcr and to come into work until the results come in, I work in a busy restaurant so I said no way, I don’t feel well as it is I have a fever and shortness of breath and I’m not infecting others. She told me if I don’t it’ll be classed as a no show and ill get disciplined for it, which is bullshit. I took the pcr test today, result will be in tomorrow and she’s asked for the direct email of results sent to her, I’m hella pissed though .. I’m about to be given a warning for no show when I’ve gave 48 hours notice and 3 counts of proof of illness. I just know when this result come back she’s not gunna b happy and she’ll need more and demand a dr note. Ugh
