i can understand completely how u feel, my dad was diagnosed with stage 4 bone cancer 4 years ago and is stil lwith us today. when he was diagnosed he was only given a couple of months to live. He is still with us today..he may not have the greatest quality of life but God is good and i have seen that everything he does is in fact for the greater good. God bless, keep faith and don't give up hope it will get u through more then u could possibly imagine
