What can I take to help with flu?

I’m in Texas and this flu going around is no joke. In just a few hours I went from feeling fine to worst pain of my life. Went to ER overnight and got Tamiflu, 600mg ibuprofen and guafenisin (expectorant) I ate garlic toast loaded with garlic and took astragalus syrup.

I am still miserable. Still have fever. My bones don’t feel like they are breaking now but I am still miserable. All my little home remedies are failing. Tips? Tricks? hacks? Prayers? Spells? Incantations?
