Breast clinic referral fears

I guess I'm looking for anyone with similar symptoms to myself having had an urgent referral to the breast clinic, by my GP this morning.

I've had tender breasts for weeks, but noticed it was far more on the left side. The right is back to normal. The left has a nugget type lump just above the areola. The areola is now darker and sunken in. It's sore and a bit itchy. 

Has anyone experienced this, or struggling with the awful wait? Urgent apps. are 2 weeks wait, but they do all tests in one day and can give biopsy results on the day. I think this is quite good. The worry is tough, especially as I'm a lone parent with a 7 year old.
