Sorry that you are having so many troubles. You may have a few things going on there. Allergies can lead to really bad sinus infection - I would get that worked on right away. You may need to get to another doc to get it treated.
Second - clean living. You didn't mention if you were still drinking and using epephedra - but my advice is to stop. You may want to mention this to your doctor - I wonder if there are withdrawl effects that are bothering you? Also ephedra is a chinese herbal for sinus problems - if you have recently stopped using it -and your sinuses are bad - you may now really be feeling the symptoms that the ephedra was covering up.
finally - panic attacks and some of the other things you mention can be part of depression. Often we need help with that also. Again - you will need a good doc that can help you sort all of this out.
But be brave!!!! You will get better with proper care. Let me know how it goes - I have suffered from many of the same things. Bad sinuses, panic episodes - I never tried ephedra.
