I have just read your post and feel so sorry that you are feeling so emotionally and physically exhausted. I do really hope that you have woken this morning feeling a little better and more able to approach your last radition therapy. It has been terribly hot and it must be so hard for you trying to be brave for your kids. Do you have anyone who is helping and supporting you?
I wish I could be there to give you a big hug personally. But I am thinking of you and praying that you will find comfort and a sense of calm in this storm.
Lots of love
