best of luck to you and mrs cfinnimore. We're going through our own cancer journey here that i'll not elaborate on but there are all sorts of things that will test you over the coming months.
Keep honest with each other, tell each other everything no matter how bad or self absorbed it might sometimes sound, generally it's no time for putting on a brave face. You might find that you're coping fantastically and then all of a sudden have a trigger that knocks you back, don't be afraid to confide in someone, that might be mrs cfinnimore or maybe someone else but if you feel the need then be sure to talk to someone. You're no good to your partner if your not in a good place yourself, you're gonna need a clear head.
It is a journey that you need to face together and one that you have a good chance of coming through but it's also easy to swamp your partner with too much attention. Give her room to breath when she needs it. I found this difficult once I realised just how little I could actually do to influence the only physical outcome that matters and spent my time trying to compensate for that by trying to do everything else.
Before you see the doctors write all your questions down, once you get in the consulting room all previous thoughts vanish. The more you know and understand the less you have to be anxious about.
Try and stay positive and I wish your partner all the best for a speedy and positive outcome.
