i'm really worried about my mum, she has a serious heart problem, she's 43 and has been smoking for around 25 years? probably more. she smokes at least 20 cigarettes a day, i'm starting to get really worried. i'm 13, i need her more then ever, i don't know what to do. i wish i could make her stop, every time i mention it she tries to avoid it and make a joke out of it, or use the excuse 'i can't help it', she'll never try to stop, i know for a fact she wont, i don't know what to do, help? :( i don't know if i'm over reacting?
