First of all, refuah shlemah.
Second, what is your mother's Hebrew name?
Third, you can quit smoking one day at a time. You can quit cold turkey. COPD is a warning your body is giving you. I know people who died of emphysema, which is an extremely painful and agonizing illness that is caused by smoking among other things. I am amazed that someone so intelligent and logical like yourself would put tobacco poison in their body. You know that smoking is suicidal.
Fourth, I suggest that along with quitting smoking, you do three other things: eat only healthy foods, get plenty of exercise and learn not to aggravate yourself (or learn to cope with aggravation in a way that does not harm your health).
