Waiting for breast biopsy results

Hi all, I'm 22 and today had an ultrasound, mammogram and biopsy due to finding a lump on my right breast. It is around 1.7cm. 
 

I go in for my results next week, the doctor was quite concerned but obviously couldn't give me a definite answer. 
 

Please can someone advise me on how to take my mind off this. I'm so worried. :(
