Just cant shake this flu and sinus infection at all

I am still sick - 3 weeks after getting this flu, my voice is still congested, my nose is still blocked and infected, I am still coughing and I still feel lethargic and sleepy. It's annoying.

I have been taking olive leaf extract, which has known anti-viral and anti-bacterial properties and while it is helping, it doesn't seem to be enough because I still sound and feel sick.

I feel so sleepy every day. No matter how much I sleep, it feels like I haven't slept enough and I want to keep on sleeping some more.

In addition to this, the abscessed tooth which had the first root canal session is hurting a bit, probably due to the sinusitis infection being more prominent on the same side as the abscessed tooth. It probably means the abscess infection hasn't properly cleared up, but the problem with my sinus infection is that when I lie down flat so they can work on my teeth, because everything is very congested in the back of my throat/nose, it makes it very hard to breath and that will affect the dental work. The receptionist understood when I told her (she could hear my voice too, which was very congested) earlier this week, on Monday, that I was unable to have the dental appointment the next day. She said she would call me in about two weeks to see if I am feeling better and to try to re-schedule the appointment.

Right now, my head is so totally blocked up and hurting me, pain in the right side of my head where my frontal and maxillary sinuses are located.  And this idiotic, abusive family I have don't help much either.

I so wish I could win a huge amount of money on a Lottery and just get the heck away from them. I wish!
