Suspected nasal cancer

Hi I'm new to this page. So basically about a year ago I started getting really bad congestion I atcually thought I just had hayfever all of a sudden then I started to get ulcers in my nose which I would pick and now a big hole has formed in my septum that is getting bigger very quickly and I feek like it's only my right side of my nostril is blocked now and when I feel like I need to clear it all this thick blood stained jelly mucus is coming out along with wot looks like membraine. I went to my gp about this she examined my nose looked very concerned and mentioned the word cancer. She has referred me to ENT as a possible cancer diagnosis my appointment is on Tuesday I'm so scared. Has anybody else had this experience
