So sorry to see you here @Karma03 - but you are in the right spot for support and information.
Please don’t feel a failure .... this is not of your making.
I would recommend you reading the story of A UK Breast Cancer surgeon here .... she was amazed at how she was affected herself after bone diagnosed, in comparison to what she’d told her patients before she was diagnosed. It is a very honest look at her own experience. She HAS had a very hard time of it, but also acknowledges the psychological effect it has on us as well as the physical effects.
http://liz.oriordan.co.uk/All the best best for your surgery and pathology results .... we all know how frightening the diagnosis is ... you have breast cancer ... It really does your brain in. Try and keep as busy as you can between now and the surgery ... even pre-cooking some meals for the freezer etc.
whereabouts do you live? City/town ... we may have members nearby who can help the you with services available to you in the town.
Do you have a buddy to go to your meetings with you? An extra set of ears can be valuable, as is the actual physical support as well. Failing that, I usually record my meetings.
I set up a bulk email to advise my friends and relatives .... I let them know I wouldn’t necessarily reply to all emails, but I would keep them updated with my progress .... it was easier than telling everyone separately. You may be surprised how many of your friends may already have been thru it themselves and may actually be very supportive of you xx
Take care, you can do this xx
