Advice sought - urgent cancer referral going to be 5 weeks instead of 2. Not sure how I will be able to cope with the wait

I have been told that my urgent suspected cancer appointment is in 5 weeks despite being told it would be a 2 week wait. I’m really struggling to function, I have 3 a lump, puckering and significant change of shap to breast. I am beside myself and not sure how to cope with this length of wait
