He started coughing a few weeks ago but it didn't seem that bad. He has been smoking for about 30 years and ever since lockdown I have noticed that he I smoking more frequently. Now he is coughing really hard and it is scaring me. He won't do anything about it because he thinks that the doctor will just tell him to quit smoking but I think there's something wrong. I am too scared to talk to him about it because he doesn't like when I bring it up and my Mum doesn't say anything anymore because my dad told her he has given up on trying to quit. I am so scared he is going to die and I can't think about anything else. Please can someone help?
