A bit scared

Hello everyone, I was diagnosed with Triple Negative (luckily only 1cm) just over a week ago after a routine mammogram and ultra sound.  I have met with the surgeon who has told me I will need chemo, then surgery and then radiation.  I am meeting with the Oncologist on Wednesday and l am scared!!  Lucky I have a wonderful family and the best friends a girl could ever ask for, but the unknown and probable hairloss is probably the worst.  Any advise would be appreciated.
