Im so sorry to hear your going through this terrible ordeal feeling alone.Know that you are not alone .I will be hear for you.I was stage three breast cancer went through chemo and radiation.I m doing ok right know. You must be very scared and confused. there are many support groups out there. Ask you dr to recommend one for you,also maybe he can speak with your family.You need them now. You are young and strong and you can beat this. as for your friends let them know that you will not let cancer define who you are. Remind them how things were before your cancer and let them know you are the same person you've always been but that life has thrown you a curve ball .I wish you the best sweetheart.
