I've just found out that my 31 year old son has started smoking. He has never smoked in his life and has always been very anti smoking. He's had a very stressful and upsetting year, losing a good friend to a sudden unexplained death and my XH thinks this is his way of coping. (There has also been a lot of shit with XH in the last couple of years which hasn't helped stress levels and upset my son a lot)
I know he is an adult and he makes his own choices, it is none of my business, but I am sad about it. It makes me worried for his health and sad that he feels bad and is using it to relieve stress.
I have had cancer - he has seen me go through rigorous cancer treatment and the emotional stress of cancer, I am struggling to understand why he would take such a risk with his own health.
He has had some mental health problems in the past, and sometimes has poor impulse control and exhibits rather manic behaviour - it has largely been well controlled and he has been well for about ten years now. He is happily married to a lovely woman and has a good job which he enjoys.
Part of me thinks I am making a big deal in my mind about something that lots of people do and that is none of my business, and I am reading too much into something that many would see as trivial, but I honestly feel very sad about it
