Hi Anthony
I am so sorry to hear about your mum.
My dad passed away in March this year from lung cancer. It truely is a terrible diesease. Not a day goes by that I don't think of him. I try to tell all the smokers I know to stop smoking but nobody will listen.
You couldn't want them to stay here for us though with all that pain. I'm sure she is in a better place now.
Take care of yourself and take some time off work to let your mind settle.
Regards
jennifer
