Everyday dizziness and head pressure for almost 2 years

Im at the end of my rope right now. I have been having constant dizziness, head pressure, headaches, visual fuzziness in right eye (occasional floater) for almost 2 years now. I have had 2 CT scans normal except it shows i have a chronic plugged right frontal sinus. EEG normal. Labs all normal. I have seen an ENT doc, didn't find anything, my GP, a neurologist ( no neuro deficits found). I have been to the doctor 30 times in the last year. They say its anxiety. I am not an anxious person. I am very happy with my life and career. But this is starting to interfere with my everyday life. I don't drive when I get too dizzy, I have had to call into work when I get bad migraines. Im am tired of feeling like crap everyday. Only health problem is GERD. I take maxalt for migraines, pantoprazole for GERD. I have tried massage therapy, and accupuncture with no relief ( and i still am continuing with the accupuncture.). I have taken meclazine for the dizziness, it hasn't helped at all. I did try taking lorazepam when the doctor said it was anxiety, it didn't help at all. It just made me sleep. That didn't solve the problem still woke up with headaches and dizziness.  I wish when I go into the doctors office they could feel what I feel like for a few days and maybe they would understand what it is like and understand me. Any ideas.
