Hi, you didn't mention what type of chemo you are having - but if applicable, ask about cold capping and whether this is an option. I'm just about to finish 12 weeks of chemo and haven't lost my hair (on my head!) as I've done cold capping. It can add to stress but for me, its been worth it not to lose my hair.
And I just reinforce what others have said - don't worry about feeling you have to be stronger. Just do what you have to do to relax and get yourself ready for treatment. Focus on you and don't worry about what others thing.
Good luck.
