Dear jenben59,
please dont give up, many of us have been in that dark place you are in now, the thoughts of been sick and knowing the battle that faces you is sometimes worse than it actually is.. you have a family that love and care for you, you owe it to yourself and then to keep going.
I too was Dx 3 years ago at the same stage and im now on my 3rd set of chemo after 3 recurrences in that time, it is so tough and i have my dark days too but i have a younge daughter and im not planning on going anywere , im going to get some quality of life out of all the crap and im here for as long as the good lord decides. My onclogist had told me we are trying to control it now, not cure it.. so, i dont believe him,im not concentrating on it, im going to live...
I can relate to everyting you say, finacially, physically and emotionally it is draining, but you are here, you are breathing you can listen to people and talk to people, you can laugh and you can cry , you are alive. Embrace it for what it is and keep going, God bless you , you are in my thoughts and prayers...
