I am so sorry this is happening to you. I definitely get the Schrödinger’s cat thing. I feel like that feline every time I get a scan and then the waiting. It feels like an eternity, frankly I think a week or two is too long in this age of technology. Trust me, you are not alone in this, even in the US, we have wait times. The corporate takeover of medicine in my area has resulted in some real hits in patient care, even worse if you do not have a primary doctor.
I love your avatar by the way, horses are the thing that help me live in the moment and reduce my anxiety when I am waiting or going through a rough patch.
I am glad you are calling and making noise for your results. Is this a regular screening mammogram or do you have a concern or a lump that is making you more worried?
