Welcome to the forum and welcome to the world of waiting! We may have some choices but they are often difficult to make (assuming you have the interest and tenacity to get all the available info in the first place) and sometimes you have to go along with ‘best practice’. Waiting is hard but the logic of settling the heart problem first is inescapable. I told most people about my bc, certainly if they asked, and my experience is people take their cue from you - so if you are happy to talk of other things, so will they (possibly relieved too). We all come to terms with the fear in different ways - my way (only once I was certain that I wasn’t about to die imminently!) was to pursue what my terror was actually in response to (partly with a very good counsellor for a short time). It has helped a lot, not just with cancer (I have been NED for seven years) but with life generally. For me, the uncertainty of what my life might turn into, all unplanned, was a real concern. Turns out to have been (so far) one of the happiest and enjoyable periods of my life. Don’t assume anything is over - treatment may be tough, but it’s for a purpose. Best wishes.
