Lump on nose septum

Hi, I've had a lump on the septum of my nose for 15 months. It's never bothered me before but since November I've had a persistent cold and the past month the actual lump has started bleed quite regular and it's changing size and look. I'm to scared to go anywhere and I have 6 young children and really bad anxiety I don't want to be told anything bad. so was wondering if anyone had experienced the same??
