Sorry you have not managed to sleep Sunny, please try not to worry too much. I had a re-call a few years ago and it turned out fine. They had found a lot of little white patches in one breast so they did another mamogram and then scanned the breast, it turned out to be scarring from a breast abcess I had when I was breastfeeding my youngest. Even if they do find something, it will be in the early stages and very treatable.
If it is any consolation I didn't sleep much either last night.
