Are mood swings a side effect of chemotherapy?
Yes, be patient. Certainly, the mood swings can be related to chemotherapy. In my book, I devote an entire section to "The Impossible Patient" -- the one who no matter how you try to give care, it's wrong -- because it's so common.
When you think of chemotherapy treatment, remember that the chemicals agents, most of them toxic, are mixing with the regular chemistry of her body. There will be changes and reactions that she cannot control -- hair falling out, "chemo brain" and these emotional outbursts. She may not recognize, process, or remember hurtful actions. I've seen patients cry during crossword puzzles, swear at squirrels, and do other unusual behavior while on chemo.
Also try to remember that these drugs take a tremendous physical toll on the body as they destroy cells. This can make her drowsy or dizzy. Her energy will ebb and flow, as will her desire to be social. Try to gauge when she's at her best and worst -- it will likely be right before chemo and the morning following, respectively. Interact more when she's feeling stronger.
Many readers have asked about feeling "powerless" as a patient or as a caregiver. As a caregiver, you may feel powerless in not knowing what to do or say -- Give her plenty of space. Have plenty of water and some bland comfort foods (oatmeal or crackers) ready to eat at all times.
The patient feels that way because of the changes in her system. With additional treatment, she should know what to expect and be able to manage them better personally. If the symptoms continue to heighten with each doseage, talk to the oncologist about it.
Give yourself some rest and some credit for helping her in this critical time. Remember you are not captive; you are helping her and have a choice to continue doing so.
Hang in there. This will not last forever.
