It’s very normal to be scared. I was scared too. The best thing to do is tell yourself you will be fine. Try and go on this journey with a positive attitude. Not everyone gets sick and feels bad. My worst part of chemo was, I slept allot. I never got sick . I also had Taxel, 16 treatments and then 35 radiation. It’s a process in which you listen to your oncologist and follow all the instructions they give you, don’t ever be afraid to ask questions . Unfortunately losing the hair usually comes within the first treatments, this is a devastating aspect but you will move on from it with time. My hair has come back with avengance! Better than before and no gray!! Your body will let you know what it needs, rest etc. Listen to your body. I wish you all the best on this journey and you will be ok
