I have PTSD. Not because my lungs are bad, but because I sit and watch my husband cough and choke everyday. He has COPD, which is directly related to cigarettes. My sister has lung cancer, which is also directly related to cigarettes. My mother had COPD and heart disease related to cigarettes. My father had pulmonary fibrosis and heart disease. I cry a lot, not for myself so much, but for the pain and stress my family has gone through because of lung disease and the fact my sister and husband are dying and there's nothing I can do about it.
