So sorry that this is looming so large in your mind and making life miserable for you.
I should say that your fear that you would not be able to cope if (by some chance) it were found that you needed some treatment may be unfounded. I have seen so many people find enormous reserves when facing health challenges - people who never dreamt they had it in them.
I am sorry too that your Mum's approach is so unhelpful - she is projecting all her anxieties on to you and fuelling the fire.
I think that we are all inclined to dwell on the worst case scenario in these situations - which is why many doctors are unhappy with these screening programmes as they can cause huge amounts of unfounded anxiety and unhappiness.
I know that this next week of waiting feels like forever - but the time will pass; and you now have someone to go with you, which is just what you need.
I do so hope that you will be able to put your worries aside a little, although I fully understand how hard that is.
Thinking of you. x
