Hi there, lovely Julie @ BowerBird11. I feel for you, and want to reassure you that, with the support of your close friends, family, and your good health care network (namely your breast care nurse at your treatment centre, hopefully you have one there), you will likely feel well supported, more at ease, and better informed as time goes on.
Treatment has come a long way, and there are many survivors, who grow stronger, find new direction, interests etc.
I had the time to teach myself the piano, the chords and melodies helped me express so much emotion that was a great healing force for me.
Your true grit friends will arrange a cooking roster, which is a godsend when you have treatment, feel low in energy, or when hubby/partner etc need support too. Say yes to any help - don't be shy, but be honest when you're too tired and don't want company.
I'm a long way on from my IDC & surgery, treatment etc, back in 2010 & happily, out the other side, (having finished Tamoxifen 6 months ago).
Good luck
