Rip to the social worker ms.nable . Its sucks that your daughter social worker social worker is gone . 20 years old is very Young age and your right addiction to smoking can be life threatening but at the time once someone is addicted to something it can be very hard to quit . All I can say to help is maby to think of good memories that you , your husband and your daughter had with her and write them in a notebook or something 🙂
