Dear Missy, I am a parent, grandparent and daughter who's father passed away this spring. The best thing you can do is give your father your love and peace of mind that you will be ok, and you will, you sound like you have a good head on your shoulders.
You are allowed to feel anyway you want and feel free to come to this site anytime you need to.
I have had bc and my husband has had non hodgkins lymphoma.
So I kinda know about being a caregiver and patient ,and what we both want from our three kids and grandkids is for them to have a happy life. we have tried to teach them about our strong belief in God and that as long as we give him control of our lives that in the end it will be ok, and we both believe in miracles. God bless you and your family it can be a very confusing time. Rocky
