You have found a wonderful site for advice, and support, from people who know what you are going through.
Feel free to Laugh, Rant, Question or share your concerns on here.
Follow your GPs advice, take your Meds, exercise, eat healthily, keep away from people with coughs and colds wherever possible, don't smoke, keep yourself and your children out of smokey environments, and you should live long enough to draw you pension for many, many years 😂
Make your house a no smoking area for the sake of yours and your children's health.
Be insistent, with everyone about this, ask them to go outdoors if they need to smoke.
Do not despair, keep a positive attitude, it really does help.
