Your mom was diagnosed at almost exactly the same time I was...and let me tell you...I am still going through the stages of grief...specifically denial, anger, and depression quite frequently. It has been two months today to her diagnosis...wouldn't you be depressed too? Her life is changing, she is probably already seeing her independence slip away as you have already made appointments for her which 2 months ago she did on her own( I know you had the right intentions)
Think of it this way, Your mom was independent and was use to taking care of you. Now imagine if you were in her shoes. If someone told you just two short months ago that your life was significantly changed and would be over soon. Her mobility is taken away, her ability to make choices, calls to dr., short term goals, long term goals...all poof...taken away. Yes she can make new ones...and encourage her to do so to help her with the depression. But coming from a PALS who is in the same boat, and same timeline...know that the stages of grief take a while to get over. It is like experiencing a death. When you know someone who dies you just don't 2 months later say you are over it and accepted it. You are still sad, angry, maybe bargaining and this can go on for years depending on how close they were to you. She will have to accept her diagnosis at some point...don't rush her....let it be in her time.
Smoking is something she can control and something she chooses to do. Yes it is unhealthy, but if it is something she enjoys and calms her down at this point...really is it going to make that big of a difference? Once the initial shock is over she may cease doing it again, esp. if she starts to notice her breathing is becoming a problem.
I wish you the best for you and your mom. I hope what I have told you helps...just wanted to give you more of a 'inside' view as to what a PALS is thinking while on this train they did not ask for. Take care.
