The single most important thing I did during treatment was try to stay positive. It was hard as heck some days but I believe that a positive attitude really makes all the difference (and there have been studies about it). I also prayed during chemo and radiation that the treatment would kill any cancer but not permanently harm any healthy tissue. Tell yourself how strong you are!
How many more treatments do you have? Do you know what your chemo cocktail is?
At first I didn't lose all my hair, just most of it on top so I tried to wear hats and left my wisps of hair hanging down in the back. I look back now and realize it didn't look any better than being completely bald (probably worse! LOL! I finally had DH shave it and eventually lost ALL hair EVERYWHERE. The plus side is that my skin never looked better! Just remember, it's only temporary.
Hang in there!
