Keep Praying

We have now been back from Mexico for a month and I have 3 chemo treatments.  I have taken oral chemo for well I am on my 5 week.  Got my cancer marker test back yesterday and it has gone up again.  we are now at 4221.  I know it isnt at 16000 were we were 24 months ago but I would really like it to be at 14!!!!!!  I have been fighting this for 24 months and out ofthe 24 months I have been doing some kind of chemo and radiation.  My body is worn out and I am tired.  It does get harder to stay positive.  I just need more strength.
