Breast cancer - Starting chemo soon - stressing!

Hi I’m new here and have just been diagnosed with lobular breast cancer.

Up to my appointment today I was told if my CT scan was clear and it hasn’t spread, I would have surgery in a week or two. Had my appointment today and found out the CT was clear (yay, so relieved!) but the plans changed to chemo then surgery in late summer. 

im now stressing about chemo. Does anyone have any advice / suggestions on what I can do to prepare please?  Thinking I may get eyebrow microblading but would be great to hear from anyone who been through it please. 

thank you x
