I don't understand what is causing these symptoms!

So I moved out of my parents house about 5 years ago. Roughly 3-6 months after that I developed a bunch of weird symptoms I have not been able to figure out the cause of. And recently they have gotten so bad that I developed anxiety-panic attacks. The symptoms mainly consist of a weird spacious feeling(feel kind of like I'm dreaming but I'm not I guess lack of clarity would best describe it), lack of focus(its hard to focus my eyes on something),lack of concentration, my nose feels congested all the time mainly on my right side(it's not runny at all),fatigue, reduce sense of smell(so bad sometimes I can't really smell much at all),sense of hearing doesn't seem to great either at times, some times it feels hard to catch my breath kind of like tightness in chest. I also developed nausea and a frequent upset stomach around this time but that has been a lot better sense taking ppi for a month.
I saw two ENT's one did skin prick allergy tests which all came back normal then offered to do a septoplasty. I received a second opinion from another ENT who did agree that my septum should be fixed gave it a 7 out of 10 for severity so I did that. It so far got rid of all the headaches I was having but I still feel like I can't breath properly through my right nostril. I also feel a weird sensation behind my nose that I'm assuming is drainage but the ENT claimed the drainage was normal. He also verified that I do have esophagitis from acid reflux but he also said it shouldn't be causing any irritation in my upper respiratory area. Also they did a cscan and my sinuses look fine.
I should mention when all these symptoms first developed I felt sick for a period of 3 to 6 months kind of like I had a low grade flu or something. I felt so terrible for that period of time I thought I was dying, I had the shakes, sore limbs, tingling sensation all over dizziness, nausea. Lost a lot of weight. The doctor said it was just anxiety and put me on anti depressants which I took and felt better but many of the underlying symptoms never went away.
Could allergies be causing these problems still? Or something else maybe Lyme disease? They have ran so many tests and have found nothing. I'm tired of feeling miserable! Please help.

Try posting this on our Lyme forum to see if you will get more answers. But do you remember being bit by a tick?

Find you a new one. A barium swallow will help diagnose you.

I'm almost wondering about molds, fungus, fungus on your nails (probably toes), what those rashes were from, your environment at home

Barium Swallowing is done by Specialists. You can get a referral from your primary doctor.

Have you been living in the same place this whole time? Do you cover your mattress with an allergy cover? How about your pillows? I've had increased allergy symptoms depending on which apartment I was in at the time. You may have mold in your place that you're not aware of which is making you sick. I just had my third round of allergy testing, which included blood tests for the first time..... I always knew I was allergic to mold, pollen, dust mites, and most animals, but now I discover that I have food allergies too.... milk, wheat, yeast, and egg white. I made the mistake of raking and bagging leaves last fall, and have had worsening symptoms ever since. Turns out I inhaled mold/yeast, have been harboring a yeast infection for the past several months... and I'm allergic to the yeast! In the past, I've had viruses I was allergic to, been allergic to drugs, and have noticed concomitant food allergies (can't eat melon ever, vinegar makes me sick when I'm having mold allergy problems, etc.). Go to a good allergist who does blood testing and better skin testing. I took allergy shots for 17 years based on two skin-prick tests, and I still have really bad allergies. My brother missed half a year of high school with symptoms similar to yours.... he couldn't get out of bed for months. They finally figured out he had lots of allergies, he started getting shots, and he was better. My experience is that ENTs don't know enough about allergies to be useful.

The symptoms got really bad I would say about 4 months after I moved out of my parents house, I then proceeded to live in that apartment for about 2 years. Then I moved to another location for about a year and didn't really notice any difference in my symptoms as far as I remember. Then I moved back to the original location I was previously at.
I have now lived here for over a year and it seems like sometime in the last year my symptoms have gotten worse. But whether there related from where I live or not I don't know and I really don't have anyway of testing. Like I said an ENT did testing for all the basic stuff both skin prick and skin shots and everything came back normal. I also do not really have the usual allergy symptoms. But all my senses feel dull and I feel like I'm a walking zombie, and as of late been having extreme anxiety from not feeling right. Doctors keep saying they think its an anxiety related problem but anti depressants don't seem to help they just seem to drug me up to the point where I don't mind my problems. But I feel the same for the most part.
So as of recently I found out my primary doctor got another job and relocated so I can't see her anymore which sucks. So I have to find somebody else willing to let me run some tests. I am thinking of having a x-ray of my lungs to make sure there isn't a problem there and seeing allergist. Also I would like to do an upper gi series see if maybe that's some how causing me to feel short of breath. It's the weirdest thing I can breath fine but my breathing feels labored like I have to really concentrate to breath and work at it. I am also still coughing up a lot of phlegm. I parents also mentioned going to the mayoclinic but I'm afraid that will just be a lost cause for a lot of money.
