Please can someone help me :(

This is my first post. I have been going through so many different symptoms and i just do not know what to do anymore. 

I have had difficulty swallowing, a mark on the back of my tongue, fatigue, weight loss, ear pain and much more. 

I have been to 5 speciailsts who have reassured me that the tongue bump is nothing but i simply cannot fathom why i would be having so many different symptoms. I am absolutely terrified that i have tongue/oral/throat cancer. 

I have booked an MRI and results will be with me by next wedesnday but i am absolutely terrified. AN ENT has put a scope into my throat and said he cannot see anything suspicious but i am still terrified. i dont know what to do anymore. I'm only 25 :(.  The Drs keep syaing ti is anxiety but i have SO MANY physical symptoms its really scary :(
