both lungs and lymph nodes

i am going on my 3rd chemo.taking adriamycin and taxitere. my only chance is slowing the cancer down or stopping it. no cure and no surgery is required. i had breast cancer 2yrs ago and was caught early/got it all. it has not shown up in the other breast.i do have fast growing kind. my question is,is there really hope??? i feel well most of the time and do all what i can before next treatment. i don't want to live depressed on what days i have left feeling good. my daughter is 30 and was diagnosed with a differ breast cancer and had surgery right after i got through with my chemo the first go around, not forgetting she just had given birth to her 2nd child. she has a hard time. iam 47yrs with 3 children, youngest still in college, 2 grandchildren and one on the way. i wasn't given any time limit but i will have another scan done to see if any improvements or on next to another meds. is there really hope???
