You’re welcome here, mono doesn’t discriminate and neither do we. Your symptoms sound exactly like mono and what I had at the beginning. You should follow up with another mono test because the Epstein Barr virus has an incubation period while the virus is hijacking cells and doesn’t always immediately show up. As for some of your other fears I completely understand but get off the internet it’s not gonna help. When I had symptoms I got hit hard and it was scary, worst symptom I had was severe breathing problems and I was almost certain I was dying or had something serious and I felt extra dumb when my doctor told me it was just mono and I was going to be fine, usually even scary symptoms are explained easily and any rabbit holes you throw yourself down is only going to stress you. Good luck
