Throat Cancer worries

Hi, i am a 20 year old female who has had trouble swallowing food for 13 months. I have been in and out the gp for this time and referred to ENT this prpcess was delayed as i discovered i was pregnant!

So far i have had a little scope that goes through the nose! And Blood tests ( I am aneamic) and a chest x ray

My ENT consultant has referred me for a neck scan and a biopsy which is in 11 days.

I am also waiting for an appointment for an endoscopy and a barium swallow. I have a lump on the right side of my neck it feels moveable? 

Basically i am worried that this is all bad news, nobody around me understands, they don't get why i can't swallow ( i take shakes prescribed by gp) apparently the gp i see hasn't heard of all this with someone my age etc... i just want to know whats going on. If anybody has been through similar/ What to expect..
