Going through chemo is tough on so many levels. The meds, the physical discomfort, the symptoms, the change in appearance and all the sudden changes in one's life brings grief and loss. Your tears are understandable and justified. They have a place in our healing process.
The chemo is working hard on the cancer cells in your body. (I could feel sparks and all kinds of sensations in my body after infusions, particularly where my tumour was located on my right ovary. It shrunk my tumour from 14 cm to less than 6 cm. All the cancer deposits on my omentum disappeared). I hope it does the same for you.
If you can get out of bed every day and go for a walk, even if it down the street & back, try because you will recover faster & feel better sooner. Daily movement, lots of water & nutritious foods are the game changers, in my experience.
Take care,
