Thanks from the bottom of my heart to each of you for your responses.
The weekend started out well.
My mom is currently in hospital and she has been for more than a week. She has been receiving blood transfusions because her blood count is very low. Her chest has been drained. Hopefully today the drain will be removed and there is a small chance she may go home, but I am not really holding my breath.
When I got to the hospital on Saturday morning she looked great (or at least as great as can be expected under the circumstances) and she was smiling and very happy that I was there. At about midday her oncologist arrived and injected some medicine into her chest that will hopefully sort out the plural effusion (see, I am learning stuff here...). This caused a bit of pain, so they gave her IM morphine as well, which made her sleepy. I spent the whole day with her at the hospital even though she was sleeping.
That night she became very nauseaus. Nausea has been plagueing her ever since Chemo started, it never seems to go away. I would almost go so far as to say it has been her most distressing side effect. It is not just for a few days after chemo, it carries on until one or two days before her next chemo starts.
Sunday the nausea was still very much present. I never saw her eat anything the whole time I was there. This has really worried me.
I have since established that it is indeed Stage IV. My dad is going to email me the chemo she is on as well as the other meds etc. I was blissfully under the impression that lung cancer is lung cancer. I did not know you get different types. I thought chemo was chemo, and I did not know you get different types.
The radiation treatment on her spine was a huge success it would seem. My mom is actually pain free as far as her spine is concerned, which is a blessing since the pain in her spine was totally unbearable to the point that she became immobile.
She is on oxygen 24/7 and has been for some time now.
I spent a lot of time with my dad as well, we spoke at length about our fears and our hopes and what has happened in the last 2 months. He is struggling, that is a given. I knew that from the start. He tries to maintain a cheerful front in front of my mom, but inside he is crying. He is tired and worried, but he was grateful that I was there.
Hospice has been great. They have been so supportive with providing some basic tools to make things a bit easier for my mom, such as a wheelchair. Counsellors have also been to visit both my parents.
Because of the side effects my mom has suffered following the chemo (extreme nausea, low blood count etc) the oncologist has decided to reduce the strength of the chemo for the next round. That should be towards the end of this week. It was due tomorrow, but my mom is really not well enough to tolerate it.
My mother is a strong woman. She is brave. She has endured much more in the last 2 months than I think I could in one lifetime. I am extremely proud of her.
What has really touched my heart is the unexpected kindness of people. From nursing staff at the hospital, to fellow church members, to total strangers, the outpouring of kindness, well wishes and practical help has been inspiring and uplifting. But the most inspiring and uplifting thing I have witnessed is my father's love for my mother. There is nothing he will not do for her. I am witnessing true love in motion.
Once again, thanks to everyone for the comments posted thus far.
