Dear VickiG
I can understand your struggle in coping with caring for your husband. I am also a caregiver for my brother who has stage 1 lung cancer. He is improving after being on Essiac Tea, a health supplement from Canada.
Maybe you should try that for your husband as it is accepted by many western doctors in USA. You can google this item to find out more.
In the meanwhile, try to pray as it does help in calming you and your husband. I am not sure if you are a catholic. My brother is a free thinker but I have drag him to church and he is quite normal quite in terms of the physical and mental condition. He is calmer and able to accept things .
Take care and do not give up cos something good may emerge . In life, sometimes we have to give up certain things but we do gain in the process.
GOD bless !
