I've gotten all kinds of radiation from x-rays from the time I was young. It takes years and years and years for anything to develop and is not at all likely to develop. Sometimes I think we just have too much information. Your HA is probably rooted in caring for 3 young children, a big job indeed.
Perhaps you can try and distract yourself by playing with them, singing with them, reading to them, going for a walk with them. Do look forward to Tuesday and until then praise yourself for taking good care of your sweet children. Wishing you peace and calm.
