I have a undiagnosed heart issue which means my blood pressure can drop suddenly, leaving me good for nothing
I felt rough this morning but went I to work as a report was due today. my boss is on a work trip all week so wanted to get it done. At 11 30 I had an episode and work made me take a taxi home. I'm now at home on the sofa resting. if I go in tomorrow the report needs to be done but after the feedback this morning it needs a lot more work then I thought 
would I be unreasonable to take tomorrow off to rest fully so I can start again on Wednesday fresh and able to do my job properly?
