Oh, sweetie, I'll keep you in my prayers.
I know what you're going through. Probably best to stay away from the Xanax.
I've noticed a relationship between sinus problems, viral infections and anxiety attacks. The physical imbalance manifests as emotional problems.
Just let your body make the needed adjustments. Trust that God has created a body that knows how to heal. Trust that He will bring you through the worst night. Listen to soothing music, such as gentle harp melodies.
May the angels surround you and may you be filled with peace and hope.
Actually in his case and mine as well Xanax is likely the safest drug to take. I'll explain why. First of all toss mental health on this and go instead to Vestibular {Inner Ear } related research. Why? Because when a person has a sinus infection or chronic sinus allergies they stand a risk of doing significant Vestibular Damage.
One of the most common and overlook sources of Anxiety Disorders is Vestibular related or actually a secondary condition and the Vestibular Disorder the primary. Severe Tinnitus, Meneries Disease, chronic sinus allergies, or even a single bad sinus infection can cause anxiety.
IF this is indeed the cause then SSRI antidepressants are not a good idea. The reason is persons with Vestibular damage are prone to Serotonin Syndrome from SSRI's because the origin is not phobic in nature or actually traumatic as many cases of anxiety are but rather Neurological in origin. The sensory system is already overtaxed. Overtaxing it more = more anxiety attacks. Xanax dulls the sensory system. Xanax also is one of the counter agent drugs to treat Serotonin Syndrome which is why I was trying to get him to answer me.
I am a Vestibular Patient with a long sinus allergy history myself. I went through this myself. I also saw my wife who has severe sensory damage go into Serotonin Syndrome. It is a very serious condition and you don't have much time to do something about it. I have had General Anxiety Disorder for 12 years now. I have taken Xanax for most of that time. My wife has severe sensory damage and has taken Xanax for over 20 years. When they tried SSRI's on her she went into Serotonin Syndrome. I have almost myself gone there.
The biggest problem with Xanax is prescribing ignorance. Many doctors will write 1-2mg twice a day. Here's the problem though. It last about 6 hours 8 tops. It yo-yo's your chemistry that way. OK now take just point .5mg of Xanax every 6 hours instead. That equals just 1 of the 2mg pills divided over 24 hours and a low but needed consistent in bloodstream dosage. Many doctors and patients don't understand the drug. If I didn't have Xanax I would be an Agoraphobic not by fear but simply not being able to tolorate sensory bombardments that trigger the anxiety. Hasn't anyone ever heard of an Inner Ear infection? They go hand in hand with sinus infections and are hard to detect. They can also de permenant damage.
I not knocking your advice in the least this is from my own experience and what I had to learn the hard way.
