I saw what he went through. I saw him getting discouraged as the months wore on him. He was beginning to enjoy what is called shutting down stage COPD and he eventually wanted to die. Actually he didn't die from COPD, cos something else killed him first. People with COPD have usually diseases resembling asthma, bronchitis, emphysema and others. It can be controlled with medication, but eventually medication stopped working and the lungs will collapse.
It is easier said than done, I know. But think again. The principal assassin is have an attack, and no inhaler.
