Bladder cancer - cystoscopy found a small tumour. I'm so worried. What do people do to cope whilst waiting for an appointment?

Hi I was wondering if anyone can help me yesterday I had a cystoscopy and the urologist said they found a small tumour and he was confident he can get it all when a TURB is done and not to worry obviously I’m worried silly and wondered what people do to cope whilst awaiting an appointment 

many thanks
