So sorry to hear you are struggling. It is such a l o n g journey and it is very, very tough to keep going back when chemo side effects are major.
I found it helped me to plan some little treats or rewards for the days just before the next chemo when I felt at my best. It boosted my energy and distracted me from thinking too much about that next chemo.
Then I would just bunker down through those awful days concentrating on the next treat that was coming when the effects eased up again. I concentrated on the fact that there was an end to this but allowed myself to wallow a bit when the days were toughest. It's very ok to feel sorry for yourself and this is a great place to let out the emotions.
Do you change chemo drugs at all? I had 3 lots of one type and then 3 of another. I had completely different effects for the second type so maybe if you have a change in your regime it may mean a reprieve from the migraines with the change.
Hang in there, you will get there and life can be good again. Deanne xxx
