Went to hospital yesterday because I’ve been sick for over a couple weeks now they said I tested positive for flu A and flu B didn’t know that was possible? Has anyone else had both at once and any tips?

So last week, I started having a fever, headaches, and fatigue, and it turned out I had Flu A. I haven’t been to school in over a week because I swear I have no idea what’s wrong with my body anymore. The fever and other symptoms have gone away, but I’ve been dealing with this horrible anxiety that just won’t go away no matter what I do.

I constantly feel like I’m about to take a really important exam or go through the most nerve-wracking situation of my life. It’s like my body is stuck in a constant state of nervousness, and I can’t relax. Does anyone else feel this way?

My brother-in-law, who also had the flu, told me he felt the exact same way, super anxious and on edge, and that he still hasn’t fully recovered from that feeling even though he had the flu two weeks ago.
Another thing is that whenever I try to fall asleep, I can’t seem to focus on actually falling asleep. It’s almost like I have multiple people in my head thinking for me, or like my brain is trying to process a million different thoughts at once. I genuinely don’t know how to explain it. Please, someone tell me you understand what I’m talking about because I feel like I’m going crazy.

There’s a pretty bad sickness going around my workplace atm. On Monday and Tuesday I felt a bit fatigued but nothing worth calling off sick for - and then, around 2am on Wednesday , I woke up with the worst fever and body aching I’ve ever had . For the next 24 hours I could not get out of bed - not a hyberbole, it was disgusting! Chills, 103 fever, hallucinations, basically in and out of consciousness. I managed to get some orange juice down me and take an ibuprofen in that period. At 5am today I woke up very lucid . Today , I have aching throughout my body still, but the level of illness I am feeling has almost halved . It’s like a switch has been flipped and the fever has gone . I’ve never had this before with a flu - usually it’s several days of fever.

How hopeful should I feel that this is going to continue? Am I truly over the peak, or might there be worse coming? I have taken today off work, but if my recovery continues on this upwards trajectory, I don’t want to waste more sick leave . I’m also considering asking my doctor for antiviral meds, but heard they will likely be ineffective at this stage.
