I need your help, please

Last week I missed 2 days of work, due to getting all the symptoms I had earlier this year (when I was sick for 3-4 months). The third day, I went to work. I felt progressively worst by the minute, and thought I did a great job at hiding it; before noon, they sent me home. I spent the weekend sleeping. Monday I went back to work, felt much better than last week, but NOT OK. Went to the gym anyway, pushed hard to do my workout, left without even starting the cardio. Wednesday, same sequence, only it was easier for me to do the workout, I was happy, thought I was on the mend.

Today, I felt like I HAD to take a nap after I got home. Slept for 2 hours, had a pretty nightmare that essentialy is telling me I’ll be sick. Last night I prepared a tea with some herbs, Himalayan salt and Iodine and used it in my eyes (they drove me crazy this week, “sandy”, itchy and burning) many times today and 2-3 times last night. When I woke up, my head felt like it was stuffed with cotton/wool and I have pressure/pain on the sides of my neck, below my ears. Everything seems congested in my head, my eyes are still almost as bad as they were yesterday. (The solution stings when I apply, but the eyes feel much better in about 5min. I feel the need to reapply every hour or so, which is what I did all day today). Oh, and I also had major pain in my lower back, on the left side only, since the symptoms started, for about 8 days now. I applied some plant tincture my mother sent me before I went to bed and it’s better, I will continue the tincture.

Quite frankly, these being the same symptoms I had before and knowing what this is, I feel pretty scared and desperate right now. I remember well the certitude I felt that I was dying, while I looked all right to almost everyone. I did not have a fever then or now and I was not mucousy at all (and yet, my dr. said it was a “sinus infection”). Are there any sinuses behind our ears? What about right above the jaw joints? Or right under the cheekbones? I would look into it myself, but I feel too sick right now, and sadly, the HEAD is the part of me that is no longer working. I don’t want to go to a dr. they would put me on Antibiotics again, but on the other hand, I don’t want to die like my friend did.

So what am I supposed to do? I was doing great before last week!

I don't think I will have access to the frequency generator, like I did this spring and I can't afford one.

Help, please!

P.S. Here’s what I’ve been on and still am on: my “power drink” in the morning:
1 cup of distilled water, 1 tsp of elderberry syrup, 1 tsp of barley powder, 2 tsp of bee pollen, 1 tsp flaxseed oil, 10 drops of iodine. With this, I take 2 Magnesium Taurate, 2 Siberian Ginseng, 1 vit D3, 2 Max EPA. Also, 1 Methylcobalamin, sublingual. When I get to work, I take 1 vit C and 1 selenium. Just tea and Iodine after 2:30, more vit C and selenium in 1 hour. That’s about it.
