That quote is perfect.
I think depression pre TX is more environmental than chemical. That is, the prospect of dying can make anyone depressed. I was severely depressed when my wife was pregnant because I was scared of dying before my son would know me. I was stuck in a huge rut. My salvation came from within since the source of my depression was entirely self inflicted.
Post TX it is more probable to be chemical since some of the drugs can cause anxiety, depression, hallucinations, delusions, etc. I had a few bouts of anxiety, which is due to the drugs and a little because I freaked out at the thought of having someone else's lungs in me -- that freak out only lasted a few minutes. So...who knows.
Obviously there are going to be the few who have a real case of depression and CF. For them, they need professional help and meds.
I would only take anti-depression pills if the source is chemical. For me, I knew I could snap myself out of it.
