Terrified this is thyroid cancer

3 weeks ago I noticed a lump in the front left of my neck and saw the GP who said suspected thyroid nodule. I’ve just had my ultrasound today and the technician wouldn’t really tell me anything about it. She confirmed it was an elongated nodule about 1.8mm but said the consultant needed to review it. So now I’m stuck in limbo waiting for the report to go to my GP. 

I didn’t come away feeling particularly reassured, in fact I feel like her not saying much means she’s thinks it is cancer. 

How does anyone cope with this waiting? My children are so young and I just keep thinking I don’t want to be unwell and them to have a life of me going off to appointments or even worse. 
I also have a parent with incurable cancer and I’m feeling very low this afternoon.
