Yeah my mum is a very heavy smoker, she has tried to give up before, and believe me, being there with her while she was trying to give up wasn't fun.
She was so angry, depressed, paranoid, and she took it all out on the first person she laid eyes on!
I wish she would stop SO bad because I can see what it's doing to her, even on the outside! Not physically, but emotionally, and I can just imagine what it's doing to her on the inside.
Sucks I really wish she would stop but there is nothing I can do.
