ugh. I don't know what is causing your chronicity... mine is allergies... I am allergic to most medicines that would normally help and have had to revert to finding herbal remedies. Please do check them out... education is a gift. (Read Dead Doctors Don't Lie, go to sites like drugfreedoctor.org...) I personally take guarana (an herb) to clear my lungs and especially for an allergic reaction (anaphylaxic) which closes my airways.

Hang tough.. you never know when something is in the wings that will help you.

Depression does come with chronic illness... and it's a day to day battle but can be won.
