@margot69- I know, the chemo and all the other crap is wreaking havoc on your health. I'm sorry. If there's a change in how you're feeling it's most likely that last thing that you had.
If you have the strength it's beyond time to sit your oncologist down and tell him that you don't feel like you are getting enough information from him. That you know that you are I'll but you need to know the truth, all of it
Can you do that?
