The last few months have been rough. I never once thought about giving up or throwing in the towel. But when do I draw the line? If things don't work out next week I will quickly become a burden to my wife and son. My 4 year old now knows that I am sick. He asks me everyday how I'm feeling. I don't want to leave him with those negative memories. Is it possible that my resolve to stay alive has now become a negative for my son? My sons mental state is really all I'm concerned about at this point in my life. I've done my best to shield him from all that as happened and he was oblivious until recently. Perhaps I'm doing the wrong thing by drawing this battle out as long as I have. Any thoughts?
