REFERRED TO ENT

Hi everyone, 

I'm 19 and I've had a neck lump for 5 months. It moves around when pushed. I went to GP twice, first they arranged bloods, nothing cam back, just slight anaemia. Went back again because my GP never followed up with me, and the other GP I saw was so lovely, checked my whole body for lumps but only have 1. She then referred me to ENT. What is the process when I go? Its this Thursday. I don't think it is cancer as I don't have the typical symptoms but I keep getting hiccups, extreme fatigue (although i do work 12hrs for the ambulance service) and pain in neck. Just overthinking and worrying myself.
