DCIS diagnosis. All new to this, need help with anxiety!!

Liryll

Hi Everybody!!  I have been reading in various topics and the more I read the more anxious I become.  I was diagnosed with DCIS and have a lumpectomy scheduled for Dec. 6th, 2017.  Radiation has been recommended after the surgery and, providing all goes well, hormone therapy after that.  At first I thought...OK, bing bang boom...all will be done and I will be fine again.  I now realize after all the reading here that this is something I will be dealing with for the rest of my life.  I am starting to get really crazy nervous!  Some women get mastectomies instead of lumpectomies for this diagnosis, I am not ready for that.  Some women decide not to have rad therapy, or not to have the hormone therapy.  I've also heard of the IORT and my cancer is in my left breast, so maybe the regular radiation therapy is not the best for my heart.  So confused and anxious now.  Anyone have any suggestions on how to calm down and start the information gathering and decision making??  Help!!
